Auto-fill inconsistencies in Android

Autofill offer on Android is very inonsistent for me as well.
I can’t understand why sometimes in apps it would not offer me autofill option. Here are some things I noticed that sometimes help (in this order of success):

  1. When autofill is not suggested, I sometimes open Bitwarden and login (fingerprint) and then when I switch back to the app, autofill suddnely appears
  2. Switch to the password field and only then autofill appears
  3. Long press the field, 3 dots menu, autofill and only then something appers (rarely works)

It is very inconsistent.
