While watching Apple TV + manhunt was interrupted with message "trouble loading content"
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....
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.
