App

Thunderbird for Android

App version

8.1

Where did you get the app from?

Google Play

Android version

15

Device model

Google Pixel 8a

Steps to reproduce

1. You already use K-9 Mail and IMAP push notifications
2. Install Thunderbird Mobile
3. Import settings from the K-9 Mail
4. Enable access to contacts and notifications
5. Send an email to your email account

Expected behavior

Push notifications will work as in K-9 Mail

Actual behavior

Push notifications doesn't work. On Android 15 it didn't display the push notification screen settings nor asked for the alarms permission.

The workaround was to switch the notifications from push to poll and back in the Thunderbird settings. After that it displayed the push notification screen settings and everything works now.

EDIT The whole thing is a big mess. When I disabled the Push switch on the Inbox folder and enabled it again, the notification stopped working. The only way was to uninstall Thunderbird and install again. This time I imported the settings from a file (because I already uninstalled the K-9 Mail) and it has finally asked for the alarms permission.

Note that the same import steps worked fine on Android 12 device and the push notifications worked immediately as expected.
