I have used Sonos for 7 years and have 2 Play 5’s, sub, sound bar and 2 play1’s on my TV and a Move, so I a little committed to Sonos. The new black app is a disaster, can’t control rooms or music. I called the help line and was told to disconnect the 3 WiFi discs we have in the house as Sonos is not compatible ( has been for the last 4 years) and if this fixed it I was to call BT and ask them to make the WiFi discs into Access Points, BT say this isn’t possible. I call Sonos helpline back and the operator clearly knows there’s a problem but doesn’t admit it. I’ve had no feedback or response since. When will they fix this? Why can’t we just get the old app back which worked? Was the black app tested?
