No longer receiving Automation Notifications in Android APP

Up until a few days ago, I was receiving HA notifications on my HA Android APP from Automations. Now they are no longer working.
I have all the Notification turn ON in the APP, but I appear to be missing one:
All Home Assistant Notification: ON
SensorWorker: ON
Allow notifications dot: ON
(I think I’m missing one)
I have uninstalled/reinstalled the HA APP multiple times and cleared cache and data each time. I have tried setting this up many times with no effect.
The errors I see in the automations and system logs are:

Executed: July 19, 2024 at 10:18:22 AM
Error: Unable to find notify service for webhook ID
Logger: homeassistant.components.automation.garage_motion_detection_notification

Error while executing automation automation.garage_motion_detection_notification: Unable to find notify service for webhook ID

I do not receive any errors or warning when setting up the HA Android APP.

Any ideas?

P.S. I have also posted this on the HA Code Github issues site, but hoping someone has run into this and has a fix - or at least ideas on what to check/test.

Thanks!

Fixed, but with a remaining issue.
I found I had half-a-dozen devices in the Mobile App Integration of HA with the same name. After Disabling them and ‘Deleting’ them. I used a different name in the HA Android APP and set it up all over again.
Now I’m getting ‘General’ notifications as before.

HOWEVER:

I cannot actually DELETE those other ‘Devices’ under the old name from the Mobile app Integration. They are Disabled, but Delete does nothing. Even after a reboot.
I’ll keep digging to see if there is a way to actually Delete dead devices from the Mobile Add Integration.
