SUMMARY
I am trying to set up Tokodon on my new phone but noticed that it just... doesn't want to work with the instance I use.
It does not accept automatically returning to the app after authorising and if I provide an authorisation token, the app enters a buggy state where I am both logged in and not logged in.

I initially thought this was an Android-only issue but it also occurs on my CachyOS-running Steam Deck.

STEPS TO REPRODUCE
1. Have an account on a misskey (or derivative) based instance
2. Attempt to login and/or provide an auth token.

OBSERVED RESULT
PC: Failed to contact server: Host requires authentication. Please check your settings.
Android: No visible error.

Nothing works on either, although Android specifically stays on the "Authorization" screen (at least graphically, the buttons seem to be properly gone functionally) while Linux continues to the home view.

EXPECTED RESULT
Works on both.
