This app is horrible!!!! The app just disappears my settings from turntables to TV surround whenever I use one or the other. We have $3500 invested in a Sonos whole house system and Sonos isn't investing in their own app. I could go on and on about the unreliability of this system, but who has the time? Just another corporation who could care less once they have your money. My advice... buy Bose!!!!
