Could you please fix this?! – Add Music to Video Voice Over Review

I am not able to add my own music to the video! When I tap on the add music button, the choose iTunes, it shows me all my music and I get to tap on the music I want...but then I can’t actually use it because the only way to get back out of the choosing part is to press cancel!!!!!!
