I would like to report that a new issue has recently appeared in which likes are not displaying on screen after being received. Specifically, when someone likes my post, and I am notified, clicking the notification will send me to my post without the like being shown on screen. Once I refresh, it is back to normal, although the time is indefinite, so it is not a matter of recency. If you are experiencing a similar issue, comment below so I can try to see if our situations are comparable/similar.
Might be a slightly unrelated issue in that case-can you check if it’s the same person liking your posts? If you receive more than three likes by one user in a short amount of time you will not be notified.
