Can't get Apple TV app to connect to iCloud

I've created a container, enabled CloudKit in xCode and added code to reference the container and save. Every time I run the app I get this error when I close the game:

Snapshot request 0x2814167c0 complete with error: <NSError: 0x28144df80; domain: BSActionErrorDomain; code: 1 ("response-not-possible")>

The app is not saved and i cannot see any action with the container. My app is built in Unity with C# code and builds with no errors.

I would appreciate and assistance!
