i have downstairs rooms running on S2. 5 bedrooms all have Play 5s running on S1 system. It used to work ok. But when I open the S1 app all it does is find the S2 system and tell me to switch to the S2 app. It happens on all my devices.
I used to have many more Sonos devices, including in other properties. I’ve sold them all since the Sonos S2 introduction fiasco.
