I downloaded iOS 8.4 this morning, and activated Apple Music. I started browsing, and found an album I wanted to add to my library. When I tried to add it, I was told that I needed to enable iCloud Music Library, and was directed to the settings.
However, when I try to enable it in the settings, I get an error saying that "iCloud Music Library can't be enabled". No further details are available. This error occurs whether I choose to "Merge" or "Replace" my device's current library.
What do I need to do to get past this error?
