Similar to other Question threads (e.g. https://community.atlassian.com/t5/Questions/Why-can-t-some-users-VOTE-on-an-issue-when-others-can/qaq-p/31523 / https://community.atlassian.com/t5/Confluence-questions/Votes-not-showing-up-in-Confluence-Questions-on-Wiki/qaq-p/271207), we might be having different issues or facing an expected behavior (points/votes for the reporter of the question). To better help you, may you specify if the feature is simply not doing any actions or if there is an error related to that?
If there are no actions, check if it happens with different questions/posts, if you are the reporter and also, the same effect in different browsers.
Hope it helps you!
