Describe the bug

I enabled Device Credentials security in the Notes app to prevent accidentally opening notes by touching homepage widget. However when I touch the widget now and scan my fingerprint - the note opens as blank and the data is gone and I have to roll back the version in Nextcloud Files to get it back.

To Reproduce
Steps to reproduce the behavior:

1. Enable Device Credentials in Security options of the Notes app
2. Exit the app
3. Create a homepage Notes widget
4. Touch any note in the widget
5. Device will ask for its biometric/pattern/pin lock
6. Unlock
7. The note that will load will be empty and the data will be gone

Expected behavior
The note should display normally

Thank you for the report, this is indeed a serious issue, i'll have a look as soon as possible.

No ide what that is.

No problem, a stacktrace is an error log that appears in case the app crashes - Since you didn't experience an actual crash, you can't insert a stacktrace of course.

Workaround

For anyone else running into this issue: Hit the three dots menu in the top right corner and choose Cancel. This should prevent data loss in case you don't have the versions app enabled.

First shot in the dark: Suspecting EditNoteActivity#onNewIntent to set a for the EditNoteActivity useless Intent with its origin at the unlocking mechanism. Maybe we can filter here for the type of intent.
