iCloud Music Library won't enable
I have Apple Music and I would like to be able to add music to my library and download songs. Unfortunately, every time I try to enable my iCloud Music library on my iPhone or Mac it says it is unavailable and to try again later. I've tried re-signing into iCloud, deleting Apple Music app and re-downloading, I also tried signing out of the Apple ID on all my devices except my iPhone 8 Plus. I tried updating my phone to iOS 12.1.1 but it still won't work. I was looking forward to using Apple Music but I am becoming very frustrated. I really don't want to have to factory reset my iPhone but if it comes down to it then I will. Please, let me know how to fix this.
