Blank iCloud screen on iPhone after 26.1 update

i'm having a problem since the 26 update, i'm now on 26.1. when going to settings then icloud, i get a blank screen. the "banner" at the top is still there. i can see the battery power, service bars, and clock. it says "icloud" at the top and has the "back" arrow. however, the rest of the screen is completely black. any ideas ?
