Is Apple Music no longer supported on 10.7.5?

Hello All,

I am running a MacPro 1,1 OSX 10.7.5 and Itunes 12.2.2.25, and this is the highest this Mac can be upgraded.

I had Itunes running fine with Apple Music and ICloud Music Library, both running fine, up until last week. I contacted Apple support and they were of no help, because this version of Itunes is no longer supported for help.

Just wondering if anyone else out there still running on 10.7.5 has seen this issue or if you are still up and running fine. Hoping to first determine if it's an Apple issue, or a personal issue.

Thanks

Chris
