Starz app not playing on any Apple TV 4K

We have 3 different Apple TV boxes in our home, including the Apple TV 4K in our family room, and the Starz app on Apple TV 4K will not play on any of Apple TV devices. I have tried restarting the Apple TV, logging out of Starz and logging back in and even removed the app and re-installed and still nothing.....all of the apps (Netflix, HBO Max, Paramount, MGM+, etc) work with no issues, just Starz...is there an issue with Starz and Apple?
