autofill not finding view id in android app

Question

We have an app where we are asking for login and password inside a fragment. It used to work like a charm with autofill. The password manager worked great with it, autofilling passwords already entered by the user.

But recently, when selecting the user/password proposition by the password manager no fields are completed.

We did not find which change in android studio SDK triggered the problem (we are using Android Studio 4.1.3 / Build #AI-201.8743.12.41.7199119, built on March 11, 2021 / Runtime version: 1.8.0_242-release-1644-b3-6222593 amd64 )

In the log we have the following hint:

AutofillManager: autofill(): no View with id xxxxxxxxxxxxx

2 times (apparently one for the login and one for the password).

We are stuck not knowing how to investigate the issue.

The layout for the form is as follow:

<?xml version="1.0" encoding="utf-8"?>
