While trying to setup surround sound on my beam and 2 x play:1’s I get an error message saying it failed to setup. I have tried resetting up all the speakers about 6 times now and it fails every time. All speakers are updated and I’m setting up on my iPhone 8plus with the Sonos app up to date. Network is fine and tested and I can get the beam working with the TV (LG) fine but no surround sound. HELP!
