YouTube works fine and has for years. Earlier this year Google started blocking some requests and due to the use of a redirect you often need to create a `New Identity` to get around it. It _usually_ helps if you visit the youtube.com homepage first, though.
YouTube blocked the network request as suspicious though I was able to view the main page fine; I did not try creating a new circuit.
The Vimeo video played perfectly fine.
I kept creating new circuits until the exit node was US, and then the PBSKids video played fine.
