Alert not showing at the bell icon

[MelvinCheung]

Hello,
I have an issue with a TrueNAS Core system where some alerts are no longer shown with the bell icon.
Eg. the pool usage is now over 80% and the 'Pool Space Usage Is Above 80%' alert settings are default (for both warning level and frequency).
SMART service is running, version is TrueNAS-12.0-U4. The alerts were working fine until about a month ago.

Regards,
Melvin Cheung

For another pool (same system) the bell notification is working fine. I even freed up space for the older pool and occupied it back up to 80%, but still nothing.

I read this:
Behind the scenes, an alert daemon checks for various alert conditions, such as pool and disk status, and writes the current conditions to the system RAM. These messages are flushed to the SQLite database periodically and then published to the user interface.

in the documentation 18.4:
https://www.ixsystems.com/documentation/truenas/11.3-U2.2/tn_options.html#alert

Is there a way to stop/start that daemon via command?

So no one has any idea what it might be?

Hi again,
