DO NOT BUY SONOS! Sold my entire system because of this horse **** app. Terrible experience, makes the system worthless because you can't control it. I stuck it out for the last few months hoping updates might help. They have not. I've not had a worse experience with any app, nevermind one that controls thousands of dollars worth of gear. I feel bad for lumping the guy with the sonos system but what other choice do I have.
