Notifications no sounds problem fixed

I have a Pixel 9 Pro fold, and for the last couple months I've had lost Notifications and Vibrations of SOME apps. No sound, no ringing, no Vibrations. Everything was activated, no "do not disturb" etc. The most anoying one was my Nest doorbell Wired 2nd gen not telling when I had someone ringing the doorbell.

After HOURS OF SEARCHING, I have found the problem on one random post on Facebook.

Google pixel Watch 2.

The Pixel Watch is eating the notification and muting it on the phone. The second I turned Bluetooth OFF, everything worked as normal.

Now I still need to find how to have both activated !

Anyone have any ideas ?
