Auto-fill service not working on Android 9 - fill request timed out

[H70N0WTE0jtPHZz86YMoJPuM3CzRiksEqBtxdqf]

I have installed the 2.0.6 version of the Bitwarden app through the F-Droid repository on my Redmi Note 4 phone running Android 9. I have enabled the Auto-fill service since it works on devices running on Android 8.0 or higher and not enabled the Accessibility service'. When I click on a text input in an app, press and hold and selectAuto-fill` nothing happens.

When I checked the logcat output when this happened, I see a couple of warning messages related to this issue

W RemoteFillService: PendingFillRequest timed out
W RemoteFillService: PendingFillRequest timed out after 5000 ms

I also have Keepass2Android app installed and when it is set as the app for the Auto-fill service, doing the same does show a prompt to auto-fill using it. So this looks like an issue with the Bitwarden app.

With the Accessibility service enabled, things work better and I get a notification prompting for the auto-fill most of the times, but I do not want to use it since the Auto-fill service is supposed to work and Google is deprecating the usage of Accessibility service. Also enabling it disables the boot time security which prompts for the PIN to boot the phone.

Does this happen in any app or only certain ones?

@kspearrin, I checked only in one app before reporting this issue. I will check in other apps and post an update.

@kspearrin, the auto-fill seems to work in some apps and doesn't work in a few others. Is there any additional information that I can provide in order to help diagnose this?
