All was great until very recently. I had a surround sound set up using a beam and 2 x play. Tv is not a smart but is decent and sound feedback is via cable from sky tv box. Changed broadband provider in feb and no issues there ….still no issues there. I have tried all of the different suggestions and cannot get the system to stay on app when updated via Ethernet. this is all really weird and after spending a couple of few hour sessions to sort it I am no further forward. Suggestions welcome but about to head for the exit from Sonos if not resolved!
