On my Samsung Galaxy S22 Ultra I have both the Sonos 1 (because of a Play 5) and the Sonos 2 app for two other boxes. When I start the Sonos 1 app it immediately says “Use Sonos S2 app”  with no other option. This is completely stupid because I need Sonos One to make my Play 5 work. 

The duality between S1 and S2 creates a real mess. Unbelievable that Sonos hasn't been able to build a single app serving all its hardware. Very poor software development.

Moreover, I have lots of problems linking my music library (on a NAS). Hard to believe.
