What do you mean exactly?
In the latest version of the mobile app (2025.5.0) I indeed have an option in Settings → Autofill which seems to be relatively new (and I think, the browsers changed something here on Android - and that is a reaction to that):
If you meant something else, please clarify.
@AE720 I see a similar development (Brave 3rd party autofill by david-livefront · Pull Request #5400 · bitwarden/android · GitHub) to what I just mentioned for Brave. That might improve autofill again?!
