Johannian said: I just gave Rob's photo a thumbs-up and it surpassed yours, so it seems to be working.
Well, Rob's photo has one more like now. Ofc it's working. That's not the issue. We're talking about photos with same amount of likes. In the past the older photo had the preference over the new upload with same amount of likes (unless admins pin specific photo). This is not happening right now.
Honestly it's not some big problem, but it's certainly a bug if Dave hasn't changed anything (and it's not because I haven't seen other things happen like this with other members).
