App version

6.400

Where did you get the app from?

Google Play

Android version

11

Device model

Galaxy A52s

Steps to reproduce

1. Have a unified inbox widget on the home screen.
2. Tap on a message displayed by the widget.

Expected behavior

K9-App opens and displays the selected email.

Actual behavior

K9 tries to open message (presumably) and then "swipes left" to show the main account inbox, regardless of what account and folder the selected message belongs to. It always return to the main inbox, even if another folder was previously open.

No difference whether message is read or unread. App reinstall also had no effect. Message selection from within the app shows no problems.

Logs

k9mail-logs.txt

Start by reproducing the Unified Inbox widget flow described in the issue on Android 11, then inspect how tapping a widget message selects its account, folder, and message. Use the attached k9mail-logs.txt while comparing widget selection with selection from within the app. Done means the selected email opens in its account and folder instead of returning to the main inbox.
