Hi everyone, as BowlerBrown just mentioned above, there were some changes made in the Sonos 10.6 software for Catalina compatibility. If you haven’t tested it out yet, go ahead and make sure you’re all up to date, and then you should be able to add your music library and find your updated playlists. There are steps here to update your music library in the Sonos app. Let us know if you see any trouble and I’ll get the feedback to the team.
If you’re still having trouble with your playlists, check out this guide for some troubleshooting suggestions as well.
