I upgraded to an IMac running Monterey, and I used the migration assistance to move my music library between the networked computers. I then used the ITunes export and import feature for Expertsapk to transfer all of my playlists from my old iMac to my new one.I then uploaded my new music location to my Sonos system, had it indexed, and was able to access my whole music collection. Imported playlists, however, were not included, and the system now displays "no selections are available" instead. I have kept up with all relevant discussions in the Sonos community, but nothing has changed thus far. I've updated my index, made new smart playlists, and built new playlists, but Sonos doesn't play anything.
