A friend of mine levelled up, so I commented saying ‘grats. I looked at their profile immediately after and there was no comment shown. I waited about 15 minutes but it still didn’t show up. When I woke up this morning, the comments still weren’t showing up on their profile, even though someone else commented as well.
I just commented on their profile, to see what would happen. The comment posted, and it showed as the only comment. When I checked from the feed, it showed up at the bottom along with the other 2.
[Edit: I also noticed that posting and “bumping” the level up feed item resets the time stamp for when it occurred.]
