Since some time in the last two or three weeks, upvotes do not show in the top bar the way they used to (like,
+10 on the achievements dropdown image for an answer upvote), at least on Super User. I have to click on the achievements dropdown image or go into my profile to see the recent reputation change. This was also network-wide, so it readily alerted me to voting going on on questions on other sites, sometimes causing me to revisit and improve them.
The reputation count (next to the avatar) is updated, but this is far from obvious.
I really miss reputation changes being somewhat prominently displayed. Where did that feature go?
Edit: It looks like this might affect only questions on sites other than the one I am currently browsing. Either way, an explanation of the intended behavior from someone in the know would certainly be appreciated! All the seemingly relevant posts I found were years old.
