By virtue of the nature of the question, I can't give concrete evidence, since I don't record my screen, but over the past few days, I've tried to change a downvote or an upvote after an edit has appeared (I know that an edit appeared, because the content of the post obviously changed), but SO has no record of such an edit, so I can't change my vote. Anyone know what's going on here/experienced similar issues?
The only thing I can think of is that there's some sort of threshold for what constitutes an edit that is significant enough to warrant a record, but that seems to be flawed. Or perhaps, there's a significant amount of lag between an edit and its recording, but that doesn't appear to be true from my experience.
Apparently there's a five-minute grace period, in which edits are not logged, but it makes no sense to me that I can vote one way, you can change your answer, and if this occurs in a certain time period, then I cannot change my vote unless an additional edit has been made.
The other posts, while very similar to this one, seem to be more concerned with when you want to undo a down vote, but what if the opposite is true and there isn't an incentive for the OP to change their post (I'm concerned with both issues). The quick fix is to edit the question and change your vote, which seems inappropriate. There should be a non-hackish way to do this.
