I made a folder with my fav lemmy apps that I tried so far, and they are sorted by favorite to less favorite. By far, wefwef is my most used and I do switch to lifoff sometimes. Also, the official lemmy app is really not bad compared to reddit’s official app. I would say try all of them and see which one works the best for you. waiting for sync and boost to launch. let me know if you have any other suggestions I haven’t tried yet.
Since you are able to login to the Lemmy website, have you tried changing your password and then logging into an app?
Also I think account server is the site where you originally created your account. I created my account on lemmy.world so that’s what I use.
I literally just changed the password on my desktop. It’s weird because there is no confirmation email or anything like that when you change it. I then grabbed my phone and on wefwef I made sure it was up to date. I typed in the password I just changed my account to on my desktop and I am getting the same error message.
