One other concluding remark here,
I's like to reiterate that this is an IOS problem. Apple Music app on my Mac works fine - I have no problems beyond a few purchases expiring, but there's really not much anyone can do about that.
For me, it's the inability to download things despite them being synced on my iphone or ipad, despite those things already existing on the cloud (pre-purchased and synced) and being available and playable on Apple Music via subscription.
Previously itunes match-synced downloads can't be removed without being deleted from library altogether. It's like the bugs are getting worse and worse.
This image below is really typical - this Basement Jaxx album is available to stream on Apple Music, I had this problem because I owned the CD and old syncs needed to be fully removed from library to free up space, and now - from Apple Music - I can't re-add it and download despite paying a subscription service.
Other occasions, it just says things 'aren't available in your region'. No bug fixes seem to have been attempted at any stage - it's been like this for well over a year.
