Morning @
sunman04
Welcome to our Community and thanks so much for your first post - I was sorry to understand that you've been having some issues with viewing YouTube via your set top box recently. As our VIP @japitts has advised, the YouTube channel was removed a while ago now to free up channel listing spaces.
There should be no reason as to why it won't load up via the apps section though. I have located your account from your forum information and can see that you have 2 boxes - are you having issues viewing YouTube on both of them?
We can see that one box was last rebooted around a week ago, the other was rebooted around 72 hours ago. We can see that your hub has not been rebooted for 44 days. Please do reboot your Hub at your earliest convivence and see how you get on.
Keep us posted.
Cheers
