New email notifications are not generated in a timely manner

App

Thunderbird for Android

App version

10.0

Where did you get the app from?

Google Play

Android version

14

Device model

Galaxy A15 5G

Steps to reproduce

1. Set "Folder poll frequency" to the minimum of 15 minutes.
2. Send e-mail to an account that is checked by Thunderbird.
3. Wait up to 15 minutes to be notified that new mail has been received.

Expected behavior

Notification should be received within at most one minute of the time new e-mail arrives to the account being checked.

Actual behavior

A 15-minute polling frequency may be okay for casual use, but that is not acceptable for professionals such as myself. I need to be able to see and respond to vital e-mails immediately.

As a test, I set up Samsung Email and Thunderbird to check the same account from the same phone. When I send an email to that account, Samsung Email notifies me within 30 seconds. Thunderbird takes up to 15 minutes to do so. I'd much rather use Thunderbird, but under the circumstances I have to use the crappy Samsung Email program because it notifies me immediately when new mail arrives.

If Samsung Email can poll the server every 30 seconds, why can't Thunderbird do the same?

Logs

No response

No source file, test, or entry point is named. Start by reproducing the notification delay on Android 14 with a 15-minute folder poll frequency, then trace the existing polling and notification flow. Done means new-mail notifications arrive within the requested interval without breaking account checks or background behavior.
