I just checked on some new Apple Music I just added this afternoon and it worked. Are you running it through Apple app on Sonos S2? Or via Airplay 2? I ran mine both ways and it worked. I am going to add a basic question but did you update your music library or have auto set up? Sometimes that will do it. Are you on phone or computer app. I am using Apple iPhone and Mac so if Windows based I can’t really help. Sometimes trying it with both will kick it in. Just a couple thoughts. Helpful or not, not sure but maybe. 

Yes, through the Apple app on Sonos 2. I have the library auto updating but also tried to push manually with no luck. I primarily use my iPad for all this but tried my iPhone with same results. 

Hmmm, you have zapped every salvo fix I have. I assume you are on 13.1.1 and latest Apple softwares? Have you deleted and redownloaded the Sonos app and/or logged out of Apple Music and log back in? That would be about all I have to do for basic troubleshooting. 

Yup!  Thanks though!

Well, as of this morning, for whatever reason, it has fixed itself. 

Hi Jim

i have exactly the same problem and have tried all the things you tried but my recent downloads still don’t appear in my Sonos library

i finally joined Apple Music a few weeks ago (coincidence?) but can’t see how that would cause the problem

Any ideas ?

 Thanks John 

Hi John,

At this point, mine appears to rectify itself after about 24 hours in most cases.  I was on Apple music from the start, so I doubt that is it.  Could try deleting and re-adding the Apple music to Sonos to see if that fixes it.  Make sure Sonos app is updated too.  If I remember correctly, another thing to attempt was to disconnect (unplug) then reconnect any/all Sonos speakers on the system.
