Unstable / Mocrosoft says they dont support iOS

Crashes on iPhone and iPad fairly often. iOS app creates duplicates in playlists. Microsoft support says "This is your trusted advisor, Karl C. Thanks for visiting Answer Desk for a complimentary consultation on Jan 15 2016 12:44 PM. I apologize if we got a misunderstanding from our previous conversation but we really cant help you regarding that issue because it seems that the issue is about your iOS. We really dont support iOS. You can try to get the songs on the Music Pass folder to save it on Groove Music." Umm what?
