Did anyone else on the 8.4 beta get a pop up asking you to start the 3 month trial of Apple Music? Just got it, tapped start and then you get the option of choosing either individual or family for once the trial is up. Naturally choosing either does nothing at this point and I couldn't progress any further. Weird though, it just popped up when I opened my music app, not with an update or anything. I should have taken screenshots, I can't get it to reappear now.
