I just "upgraded" my ipad to ios 8.3 and now I can't launch youtbe videos from email links. I get "Error loading Youtubelink". I tried logging in and out of youtube with no liuck. Any thoughts?

Thank you for using the Apple Support Communities

What I would suggest doing is uninstalling the YouTube app and reinstalling it.

(Press and hold the icon until it goes into jiggle mode then press the "x" on the icon to delete)

If this does not help, you may also try resetting your device. This won't delete your data stored on the phone.

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

Alternatively, you may go to Settings - General - Reset - Reset All Settings
