If this helps the engineers working on this. I tried un-sync the library and re-sync. Twice. Once without a reboot, and once with. I tried rebooting my router (even though Apple Music is the only thing not working). I tried disconnecting from WiFi and Bluetooth and turning it back on. I uninstalled and reinstalled the Apple Music. Today I tried turning off Lossless (even thought that would defeat the purpose of having nice DACs). I thought that worked, but the Apple Music app quickly froze. I obviously tried to turn off the iPad and back on, multiple times. I'm willing to try anything, other than refreshing the iPad back to factory. Others have tried, and that doesn't work.
I pay for Apple Music a year at a time, so I can't just cancel it. Please upgrade this issue to be taken care of ASAP.
This doesn't seem to be a data transfer issue, as after re-syncing my library, it all came back quickly. The Apple Music app itself stops playing music and becomes unresponsive (freezes).
