The YouTube iOS app stopped working a while ago, I suppose the backend API changed.
But YouTube still works via Safari on the iPad 4.
I generally keep JavaScript turned off in Safari on that old tablet; I think it's a RAM limitation but it could simply be that the JavaScript version is too old. Many sites just don't work. But with JavaScript enabled, YouTube still does fine.
