After multiple threads (since closed) the app still defaults to the wrong room when it's started. Yes, I have a den and yes I occasionally play music in it. But 99 times out of a hundred I listen in the living room. App starts up showing den even if music is on in living room. I've renamed the rooms, deleted and reinstalled the app. No avail. I get why the CEO got ousted - he should be. Hopefully Conrad can return the Sonos app to a user friendly, intuitive and working piece of software.
Rant aside - if somebody has a fix I will humbly use it and apologize.
