App stuck updating
The Keynote app on my iPhone 6 won't complete the update. The icon is stuck with "Loading..." below it. I have tried to redownload from App Store numerous times, as well as rebooting the phone. I cannot delete the app by holding the Home button as when I click the X the pop up says: Delete "" , (there's no app name) and clicking okay does nothing. When I go to Preferences - Storage I can find the App listed (with no name) and delete it there. After deleting the app, reinstalling from App Store hangs at same spot.
iPhone 6, iOS 8.3
