Why Can't I Comment on LinkedIn? Causes and Fixes
Why can't I comment on LinkedIn? Usually it is the author's comment controls, a block, a temporary limit, or a stale app. Here is how to tell them apart fast.
By Animesh Kudake, Co-founder, Apna Project
The short version
- The single fastest test is whether the problem follows you: if you can comment on someone else's post, the issue is that post, not your account.
- LinkedIn lets every author choose whether anyone, only their 1st-degree connections, or no one can comment, and they can change it after publishing.
- A missing comment box with no error message almost always means comments were limited to connections or switched off.
- LinkedIn says it may limit how many comments a member or Page can make in a set period, so a burst of commenting can pause you temporarily.
- If the comment posts and then vanishes, suspect filtering or removal rather than a technical glitch, and rewrite it without links or repeated text.
Blocks, restrictions, and accounts that no longer exist
If commenting works everywhere except on one specific person's posts, something is set at the account level rather than the post level.
A block is the cleanest explanation. When someone blocks you, their content becomes invisible and un-interactable to you, and LinkedIn does not tell either side. Authors can also delete individual comments and report accounts, so a pattern of your comments disappearing on one person's posts is worth reading as a signal rather than a bug.
The other quiet case is an account that has been closed or restricted. Posts from a deactivated profile can linger in feeds and search results while every interaction on them fails. Nothing to fix there.
When LinkedIn limits how often you can comment
LinkedIn's own help documentation states that it may limit how many comments a member or a LinkedIn Page can make in a certain time period, as a safety measure. It does not publish the number, and we would not trust anyone who claims to know it precisely.
What we can say from watching a lot of accounts is that the trigger is usually pace, not total volume. Twenty comments spread across a working day behaves very differently from twenty comments in four minutes. If you have just been on a commenting sprint and everything stopped working at once, wait a few hours before you conclude anything worse has happened.
The same help page notes that excessive commenting or the use of automation tools can reduce how visible your comments are. That is worth taking seriously, because a comment that posts successfully but reaches nobody is a failure you cannot see. If your comments are landing but nothing is coming back, the problem is different from the one this post covers, and LinkedIn comments not showing walks through the visibility side.
We should be straight about our own position here. LinkedIn's User Agreement prohibits third-party automation, and Commenti operates in that gray zone. We say so on our own site rather than pretending otherwise. What we build for is reducing risk: daily caps, pacing between comments, skip filters for posts that should not be touched, and an approve mode where nothing goes out without you reading it first. Our plans cap deliberately low, at 20, 40, and 60 AI comments a day for $19, $29, and $49 per month billed yearly, because a cap you cannot exceed is the only version of restraint that survives a busy week. Reduce is the honest verb. No tool can promise immunity, and any tool that does is selling you something.
The dull technical causes that feel dramatic
Before assuming a penalty, clear the boring ones. In rough order of how often they turn out to be the answer:
- A stale session. Log out and back in. This fixes a surprising share of "the button does nothing" reports.
- The app version. Update it, or try the same post in a desktop browser. Commenting bugs are frequently platform-specific rather than account-specific.
- Browser extensions. Ad blockers, privacy tools, and LinkedIn add-ons all inject themselves into the comment box. Disable them and reload.
- A LinkedIn incident. Occasionally it is genuinely broken for everyone. If it started in the last hour and nothing you do helps, wait.
Run through those four before you spend an afternoon worrying about your account standing.
If the comment posts and then disappears
This is a different failure and it deserves its own diagnosis. A comment that submits successfully and then goes missing was either deleted by the author, caught by a filter, or removed under LinkedIn's content policies.
The pattern we see most often involves outbound links. Comments carrying a link get treated with more suspicion than plain text, which is exactly why the "link in comments" habit exists in the first place. Copied or repeated text is the second most common trigger, especially if you have left the same congratulations sentence on nine posts this morning.
The test is simple: write the same point in your own words, with no link, and post it again. If it stays, you have your answer. If you want the comment gone on purpose instead, deleting a comment on LinkedIn covers both your own and other people's.
What we would actually do about it
Work the list in order and you will usually land on the cause within a minute: try another post, look for the missing box, check whether it is one person or everyone, slow down if you have been fast, then clear the technical noise.
The thing worth internalising is that LinkedIn rarely explains itself. There is no error message for connections-only, none for a block, and none for a temporary limit. That silence is what turns a two-minute setting into an afternoon of anxiety. Once you know the four categories, the silence stops meaning anything at all, and you can get back to the part that matters, which is having something useful to say when the box does open.
Frequently asked questions
Why is the comment button missing on a LinkedIn post?
The author almost certainly limited comments. LinkedIn gives every poster three options, anyone, 1st-degree connections only, or no one, and they can change the setting after publishing. When comments are restricted you usually get no explanation, just a missing box, so check another post from a different person to confirm.
Can someone stop me specifically from commenting on their posts?
Yes. If a member blocks you, you cannot see or interact with their content at all, and authors can also remove and report individual comments. There is no notification either way, so a comment box that works everywhere except one person's posts points to a block or a restriction on that account.
Does LinkedIn limit how many comments you can leave in a day?
LinkedIn does not publish a comment number, but its help pages state it may limit how many comments a member or Page makes in a certain time period to keep the platform safe. In practice a fast burst of comments can pause you for minutes or hours. Slowing down usually restores it.
Why did my LinkedIn comment disappear right after I posted it?
Either the author deleted it, a filter caught it, or it was removed for a policy reason. Comments with outbound links, copied text, or anything that reads as spam are the most common casualties. Rewrite the point in your own words without a link and post it again to test.

You have something worth saying, you go to the comment box, and it is not there. Or you type a reply, hit post, and get an error you cannot decode. Or the comment appears for a second and then quietly vanishes.
Why can't I comment on LinkedIn is a question with about six different correct answers, and the fix depends entirely on which one you are hitting. The reassuring part is that most of them have nothing to do with your account being in trouble. The most common cause by a wide margin is a setting the person who posted chose, and you can rule it in or out in roughly ten seconds.
We spend our working days inside LinkedIn comment threads building Commenti, so we have run into every version of this. Here is the order we check things in.
First, find out whether it is the post or you
Open a completely different post from a different person and try to comment there. That one test splits the problem in half.
If the second comment works, the first post is restricted and your account is fine. If you cannot comment anywhere, the cause is on your side: your session, your app, or a limit on your account. Do not skip this step. Most people who assume they have been restricted have actually just met one author's settings.
The author's comment controls are the usual answer
LinkedIn gives everyone who posts three choices for who may comment: anyone, 1st-degree connections only, or no one. The setting can be picked before publishing and changed at any point afterwards, and once chosen it becomes that person's default for future posts.
That last detail explains a lot of confusion. Someone sets a post to connections only during a hiring push, forgets about it, and every post they publish for the next year quietly excludes everyone who is not connected to them.
What you see depends on which option they picked:
If you are the author and you want the box back, the fix takes two taps, and we walk through both the desktop and mobile paths in how to allow comments on LinkedIn posts.
