I'm loading https://lemmy.ml/c/worldnews@lemmygrad.ml and the username display in the top right is showing other people's usernames, not mine. It showed one, and I refreshed, and now it's showing another. Here's what is showing right now for me:
Edit to add just to show that it's changing:
That doesn't make sense. If it was my browser cache it should (a) show my username, and (b) show the same username every time. I did do forced refreshes (without browser cache), as well as used an incognito window (where the same exact behavior happened).
