Considering this user made an account on lemmy.ml to post this, and the community in world was made by the same user with a world account, maybe they don’t understand the federation aspect correctly. It seems to happen a lot, and it’s frustrating because it leads to one huge instance in lemmy.world.
The web browser works fine for me, and then I don’t have a other app on my phone. I’ve tried a bunch of different apps, Jerboa, Liftoff, Wefwef/voyager, and connect, and I keep coming back to just viewing it in browser. Haven’t tried Sync because the idea of wilfully putting ads into a thing that doesn’t have them is disgusting to me.
