QC35 II does not respect the notification/ringer volume settings on my Pixel 3
When I connect my QC35 II's to my Google Pixel 3 phone it always plays an (often loud) audible sound when I receive a notification. This happens even if I've set my ringer/notification volume to silent or vibrate. Even worse, it totally ignores when I've set my phone to "Do Not Disturb." I've noticed that after my bluetooth connection is established, all notifications go through the "Media" volume channel rather than "Ring" (what it should be).
On top of that, after I disconnect my headphones, my notifications continue to go through my "Media" volume channel, which means I will receive very loud notification sounds through my phone's speaker. The only way I can silence these notifications is to either turn my Media volume all the way down (which means I can't listen to anything), or I have to reboot my phone. Obviously none of this is desirable behavior. I've tried resetting the connections on the headphones and deleting the pairing from my phone (to no avail). I've also tested other bluetooth devices (such as my car bluetooth and a different pair of non-Bose headphones) and they don't exhibit this behavior.
I've tried Googling for solutions but I'm coming up empty. Does anyone have any suggestions or would anyone like to commiserate with me?
