Why is my new Apple TV suddenly not showing my purchased TV shows?

I was having this same issue. I have Restrictions turned on so my kids couldn't buy anything. It's supposed to ask for a passcode (which it does when buying apps). Trying to buy something on iTunes just caused the spinner to spin forever. I turned off Restictions and it worked the first time!

You are not alone. I have seen the same thing. No purchases for tv shows but I can see my favs and can access my stuff from search. Which probably means one or more of the servers that own our data is bad in some way or another.

Going to try logging out/in again as that has worked in the past.

Good luck.
