iphone 7 plus apps won't stay open

Hi,

I just upgraded to Iphone 7 Plus. The apps that now come on the phone: Clips, Garage Band, Pages, Numbers, Keynote, and Itunes U will not open all the way. Soon as I click them the partially open and immediately close. Any idea what's wrong? I've signed out of my Apple ID account and back in like someone suggested. All other apps I had on 5s are working fine on new 7 plus.
