Some (or maybe all?) of the time, posts I've previously voted on seem to show now visual indicator. When I click again, the number changes in the opposite direction as expected meaning I undid some previous vote. I'm just using this in firefox on PC. Is anyone else seeing this? I can definitely see the style directly after I vote but before I refresh the page. Thanks!

Edit: of course refreshing this post I can't reproduce it. Not sure if it's because it's my post or if there is some time lag or if it's only other instances or something.

I have noticed intermittent problems with this too. Something to do with caching, I think. Good to know I'm not the only one!

I have been seeing that for down votes for a month or two now. The vote is indicated when I place it but if the page reloads it is not indicated. Up votes are indicated reliably - at least, I haven't noticed any problem with them.

I guess this could explain why I recently saw a comment having "-1" downvotes.
