[BUG] OneDrive authentication fails

Checks

• I have read the FAQ section, searched the open issues, and still think this is a new bug.

Describe the bug you encountered:

I have my KeePass database on OneDrive, so I can use it on my laptop and in my phone and stay synchronized.
All of a sudden - that is: after automatic upgrade of KeePass2Android - the file won't open anymore and no error message is shown.
When trying to open it as a new database, when I select OneDrive, I get the error "authenticating not successful".
I don't know if the grey display of the OneDrive icon has anything to do with it; only the Google Drive icons have color now.

Describe what you expected to happen:

I should be able to access my OneDrive folder/file. A couple of days ago it still worked (in a previous version of KeePass2Android). Or else the app should not have been automatically upgraded...

What version of Keepass2Android are you using?

1.15-rc1

Which version of Android are you on?

12

Start by reproducing the OneDrive authentication failure on Android 12 with KeePass2Android 1.15-rc1, comparing it with the previous version if available. Trace the OneDrive sign-in flow and use the reported missing error message as a diagnostic clue. Done means an existing KeePass database can again be opened from OneDrive, with a useful error shown when authentication fails.
