@YouTube your app doesn't work offline on an ipad. I press "library" and it always says "offline: watch downloads in library" and I click go to library again and it doesn't work. What is the point if viewing offline if you can't access your library offline?
We'd like to help. Just to confirm, do you have any pending updates available for the app on your iPad? Also, try signing out of the app, restart the device and sign back in to check if that makes a difference. Let us know.
