Edit: I'm done, returning the products! App is impossible to use, don't have the time to reconfigure everyday the system. Sonos Arc + Sub Gen 3 + 2x SLs Experience: Awful!!! Countless errors while using the app: can't connect to Sonos, room offline, sub not found, one of the stereo speakers offline and so on. Impossible to have a pleasant experience while using the other services, a lot of errors (can't play, can't add to the list, can't connect to the service Deezer, Tidal, TuneIn etc.)
