Apple TV videos not loading on my LG TV

Difficulty watching Apple TV shows on new LG TV.

Message says unable to load video check internet connection and try again.

Internet is connected and working, all other streaming services working.

Apple TV app updated, still having same issue.

This is annoying, we are paying for Apple subscription, after much messing around we can watch an episode only to have the same issue when trying to watch the following episode... can anyone help please?
