I love my Sonos setup and haven't had any issues
I've got an Arc, Sub Mini, One SL surrounds, and Ace headphones. I haven't had a single issue with anything.
My home theater setups work exactly as it should. Audio Swap to my Ace headphones and back to my Arc has worked painlessly. Playing my Apple Music library from the app to my setup has had no issues. The app itself has been perfectly responsive for me.
It's just been a great experience all around.
This post is not meant to discredit those having issues. I sympathize with everyone that are SOL right now. But I also think that it's important to point out that this certainly isn't affecting everyone (or even the majority of customers?). I wouldn't have even known there was anything "wrong" with the current state of Sonos if I didn't check this sub.
