Hello from Finland,
I have been using Sonos system for 13 years. I have six different Sonos speakers. Half of them legacy S1 -only speakers and half modern ones. I finally realized I have to move to S2 and forget old speakers. I just realized that Sonos playlists don’t move from S1 to S2. I have couple 500 song playlists. I opened S2 and uppgraded new speakers to S2. Then I saw that playlists don’t move. I figured out that I have to manually move playlists to Spotify. Half a days work but possible. I opened S1 and started moving playlists by hand. I realised that I don’t have inaf time to do that at that day so I came back to do that couple days later (today) and S1 don’t open. It just says open S2. I deleted S2 app and cut new speakers from electricity. Won’t help. Can’t get S1 to open. See that old speakers flashes at app before it says “Us S2 app”. Are now old playlists destroyed? Can I do something to get old lists back? My wife will kill me for this..
