switch to a VPN that has a native app for Apple TV.
Which VPN? Does it work with HULU and other streaming services too
It worked! I downloaded the app to my Apple TV and logged in using my email credentials.
IPVanish. So far it has worked with Hulu
It worked for me too!! Just read your comment, tried it, and worked! Put my network settings on automatic, turned on the express vpn app on my Apple TV, logged in with my username and password and selected the region and bingo!! 
Any idea if this vpn works with others - peacock, paramount, etc?
Yes, Netflix, Hulu, Peacock, Paramount, BBC iPlayer
