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.
Let me see why you had to do it more than once. Really weird.
Looks like you might have figured it out below in your discussion with RustedSwitch! Thanks for the quick response.
