Cannot share photos and videos from Photo app
Today I have saved several pictures and taken several videos with my iPad's camera. However, when I attempt to share them (via the box-with-arrow-pointing-up button) nothing happens. If I try to send an email the email successfully sends but nothing appears in "Sent Mail" or the other email's inbox. I have also tried to share via Facebook, with no results.
I have a good internet connection and an iPad Air 2 running iOS 8.1.1. What could be wrong with the app and how can I fix it?
