App store version is up.
If you are on Lemmy.world, you need to update your JWT token. Sorry, this was not intuitive and there is no proper error message. This is my fault and we seriously just never got around to this.
Please go to “Manage Accounts” and then tap your Lemmy.world account. Hit “Edit Account”, enter your password, then hit save. You should be back up and running.
Thanks - just managed to sort it. I was logging in with my email before, but I noticed it was now asking for the username.
All sorted!
