To edmountain: I’m talking about the list that shows in my Sonos app. For a year now, if I was on YouTube via my phone or laptop, and “Liked” a song on YouTube, it would also show up on my Sonos app on my phone under YouTube Playlist, then Liked Music. No more. The last one that shows up there is one I “Liked” on YouTube over two weeks ago. I have since “Liked” on YouTube two more songs, and they aren’t in my Sonos app under YouTube Music “Liked Music”. Thus, I can’t play the latest two on my Sonos speaker.
I can’t figure out what has changed.
@J.A.B. That's what I'm talking about as well.
When I like a song in YouTube Music, it immediately shows up on Sonos in the YouTube Music "Liked Music" playlist.
You keep talking about liking songs in YouTube as opposed to YouTube Music. Hence my suggestion to check your YouTube Music app settings to make sure your YouTube Music account is configured to acknowledge those likes. If your YouTube Music account does not acknowledge YouTube likes then there's nothing Sonos can do.
