I’m having a lot of trouble since the new app just like a lot of you guys. I’m though having a problem where my Arc keeps disappearing in from the system. First sign is that I can’t find it under Airplay. When I open the Sonos app I’m meet with the message seen in the picture (system found and Arc and asks if I want to set up). If I then wait a few minutes the Arc completely by it self comes back to the system. Anyone else had this problem?
