Three things:

1. I've flagged your post for moderator review for language that violates the rules of conduct.
2. If you’d like to repost in a more civil tongue describing your issue(s) I’m sure we’d be willing to assist. 
3. As of now as far as I’m concerned...you’re on your own

“I can’t help you you used naughty language”  

is that how you dodge concerns?  Lazy lazy workers. Everyone sell their stock in Sonos (if anyone is actually unintelligent enough to actually have bought this ) if you can read this. This company is going down the toilet. Fast. 

​@AjTrek1 doesn’t have a ‘Sonos employee’ or other Sonos badge next to their name. They may be a lazy employee, I don’t know, but they don’t work for Sonos. 

This is my last comment to you..

I’m not a Sonos employee. I’m not paid for the assistance I provide. I participation in this community is strictly voluntary as is that provided by 99% of the community members. The other 1% being Community Moderators or Staff. To be clear those designated as Moderator or Staff are also not responsible for Sonos development nor code/script writing. Although they too will assist with Sonos User issues that are within their scope and knowledge base.

So once again if you’d like assistance rein-in your language and communicate in a polite manner.

Delete Apple Music from Sonos app. Maybe delete the app , reboot your phone for good measure. Then try and add it back.  
 

The app is not back to pre disaster reliability but you shouldn’t have to reauthorize AM continuously IME.
