Apple TV not playing shows on MacBook Air after macOS Tahoe update

I cannot play any shows in the app or when I log into my account on safari or chrome.

I have updated to Tahoe.

I have logged out/logged in/restarted.

I can log into my account but when I click on a show it will not play.

On the app -sometimes a screen flickers like it's going to play but the disappears in less than a second (although it doesn't even do this now that I have updated to Tahoe - it just doesn't do anything when I click the show.

If I am in google or safari, a black screen comes up like it will play but then nothing plays.

I was using it perfectly fine last night and cannot think of anything that could have changed.
