I never received a prompt to enable iCloud Music Library. I cannot find any option for it in the preferences. I have the latest version (188.8.131.52). I search the iTunes help and it makes no mention of how to enable or disable it. The problem is that I have Apple Music subscription and I have IML enabled on my phone. However, I also have 20GB of music that I had previously synced to the phone. That music is still there and everything works fine on the phone, however, I cannot add more music. In iTunes, when viewing the phone music, it claims that I am using iCloud Music Library, so I should theoretically be able to play any music in my iTunes library. However, I cannot. No music other than what I had on my phone originally is showing. iTunes will not allow me to sync more music. My iPad had no music on it. I enabled iCloud Music Library, and now I can see all the music that is on my phone, but nothing from iTunes. In short, iTunes does not seem to have IML enabled and there is no option to enable it. What am I missing? I am not going to enable and disable IML every day just to change my playlists and add music. Something isn't working properly. edit: I found something in the help file that says I should have an option in preferences called "iCloud Music Library checkbox". Instead, I have an option that says "Show Apple Music" in that place. WTF?
