I have a spit system, numerous connects, boost, play1’s all have been updated to S2. I have an S1 pair of Sonos 5’s. My iOS S2 app locates the S1 5’s and won't launch the S2 app. S1 app launches fine. This is very frustrating. I may have to reset all my S2 components and downgrade them to the S1 app. Anyone else having this challenge? My Mac computers S2 apps are stable and recognize my s2 equipment. The S1 mac app won't recognize my S1 5’s. Arg!
