Resolved HomeKit not sending notifications

[katbel]

Since iOS 15 is out I don't receive anymore notifications on my iPhone iOS 14.7 from HomeKit Circleview 2
I updated the HomePod mini to the latest update, thinking to do the right thing, WRONG
The iPhone shows the video clips on the HomeKit app but it's not sending/receiving any notification
I tried everything , restarting HomePod mini hub, iphone , resetting the camera.
Nothing, just a lot of frustration. Anyone else having issues with notifications?

Update: I tried to add an automation like "Play audio" thinking to have to choose a " bell, horn, frog..." or similar
or even my own music.
This is what I got ?
