I know this has previously been discussed but not exactly the same as me. Im fairly confident with tech but not in depth. I have 4 sonos play 1's and have had them set up without a problem for months. My wife and I have all apple devices, phones, ipads and mac book. All worked flawlessley with sonos. I have now got a samsung galaxy s7 and it doesnt work at all with sonos. I have re installed app, turned router on and off, cleared the cache etc. The app still says it cant find my system. Even when it asks me to press the two buttons on top of speaker the app cant find them.
So frustrating as sonos was meant to be basically plug and play, surely the app developed on android should be just as easy as apple.
