Apple TV having trouble loading content

Similar situation with me with Apple TV 4K. All apps will play content except not the Apple TV+ shows. After selecting something to play There's a problem loading content box comes on screen. TV based Apple TV app will play, but I should be able to watch through the actual Apple TV 4K. Restarting things does not appear to have helped. Apple seems to have an issue that needs investigation. Thanks.

So I hope this may help, Ive had same message and I removed app from my Roku and then reloaded it and signed in fresh and it has started working....
