breaks my system, play1 which were s1 compatible now no longer, cannot add large music library, accepts small SMB music library but often cannot play the mp3 files, blind to dlna shares, cannot connect SONOS wirelless to ASUS XT8 mesh without a device ethernet cable wired to get SONOSNET. SONOS ONE 2.4 GHz radio apparently inferior to Play1 as it kept dropping off SONOSNET! S2 controller missing: backup restore of app and device settings, log file, no release notes of changes
