Same or similar issue has been raised before but I could not find a solution that worked for me.
I want to play tunes I have stored in My Library through my Sonos system.
I subscribed to Apple Music (though all these tunes are downloaded from CDs I purchased), I added Apple Music to my Sonos list of music and content.
I now see that some tracks (a lot) are greyed out and not playable through Sonos. They are playable through Apple Music.
I do this through an iPhone.
I was trying to resynch/reindex (?) Apple Music to Sonos as I recall having to do it when I first set it up but I cannot remember where to do that (if even this would help).
I saw some info about Apple Music needing to recognize my tracks (if they don't have it in their catalog, then that might explain why it’s greyed out) but these are the tracks I am looking to play, these are “mine” if you will.
Many thanks in advance
