iOS Apple Music issues 14.3 upgrade

Hi PRYSAR,

We understand that you're having some problems with Apple Music after updating to iOS 14.3 and we want to help. When you say the music has been deleted, are the songs missing from your Apple Music library, or has content been deleted from your iPhone? The reason we ask is that iOS will sometimes delete content that can be downloaded again, if it needs to make more room for an iOS update or prevent the iPhone from running out of storage space. We have more information at How to check the storage on your iPhone, iPad, and iPod touch

Please let us know a few more details, and we'll keep working on it.

Have a great day!

I have updated my iphone 7 with ios 14.3 and Apple Music now tells me that my "Apple ID is already being used with a different subscription." Songs will not play or are incorrectly tagged (an album will play with song titles changing but with the same music over and over again, etc)

Help!
