Ah I found the issue, I think. When I enter username and password, it says “not using password” and doesn't let me sign in. When I restart the app, I says I am but only in settings.
That’s extremely weird. I’ll do some testing and see if I can replicate the behavior.
Okay, so I was able to replicate that behavior. Your solution is to set a password at https://wasteof.money/settings, ensure that it’s enabled, and log in with that.
