If I go to Settings -> Music and then disable the iCloud Music Library switch, it will just revert back to the "on" position, once I leave the settings or switch over to the Music App. This is a really bizarre problem. I wanted to disable it, then manually clean some songs from the iPhone and then start over again, but it won't let me. While other people have problems switching the service on, I am unable to switch it off. Any solutions to that problem, except to reset the whole phone (which I will probably do, but I'll lose my Apple Watch Activity calibration data)? Thanks so much! Update: Inside the Music App I now signed out of my Apple ID Account. That enabled me to turn off iCloud Music Library...but now I have 42 songs on the iPhone that cannot be deleted. And parts of Apple Music, like the recommendations, still show up. All other devices are integrating really well, but my iPhone has become a mess.
