BTT, still no mention of this issue in any of the Sonos communications 

I have the same problem on a S24. Weird thing is that although notifications are allowed in app settings and preferences, the app does not show when going to system settings/notifications. So notifications do not work at all. Just another new app hick up, unbelievable

Gotcha, I was curious whether my issues were Pixel-specific, I don't see them mentioned much in this forum. 

It's peculiar to me that Sonos never mentions anything about the Android widget or notifications in any of their communications to us. It's like they've been specifically instructed not to use those terms.

It makes me think either those issues are very low priority for them, or they don't know how to resolve them yet.  Either way, very concerning. 

Try this thread for possible Pixel 6 solutions:

The only solution shown there is to roll back the Android app to an older version, which I did at one point but can no longer do. Once the firmware on the speakers gets updated past a certain point, the older version of the app becomes unusable and you are forced to update the app if you want to use it at all.

(BTW, that's not a thread you linked, it's the search results for a "Pixel 6" forum search.)

Really…you’re looking for help and you’re correcting word/phrase usage Good luck to resolve your issue

My point was, it seems like you are not here to provide help but to suggest people's problems are theirs to fix. And looking at your recent posts, that checks out.

We already know there is no current solution to these particular issues. 

With 90% of the app supposedly fixed, where is the persistent notification? As mentioned already, there is still no mention of this feature.. this was one of features I used most. Still  waiting...maybe it's in the next update..
