Q: Itunes u not working at all

Hello there Rorox89,

It sounds like your iTunes U app is not functioning correctly.

I want to recommend first, closing all the running apps on the device.

1. Double-click the Home button.
2. Swipe left or right until you have located the app you wish to close.
3. Swipe the app's preview up to close it.

From: iOS: Force an app to close

Then restart your phone and try again.

iOS: Turning off and on (restarting) and resetting
