I recently signed up to the 6 months free Apple Music and have had so many problems and I just can't get it to work. I have a Huawei P9 and have downloaded the apple music app. I have finally managed to sign in using my apple ID when I go to try to play stuff there's a tab at the top to say "joined through EE?" I click on that a purple screen comes up then minimises again and nothing happens. I didn't have a subscription to apple music before just the apple ID. I don't know how to progress this. I keep uninstalling the app and re-installing but I still can't get it to work. Any ideas?
