iPhone 11 Pro - Camera App in Landscape --> Screen Mirror Apple TV not working

Using an iPhone SE I have no problems screen mirroring to my Apple TV using my Camera App in Landscape.

However, with the iPhone 11 Pro, the view stays in portrait mode on the TV. Not feeling very Pro.

Toggled orientation lock off/on, tried using some obscure camera apps, and some would work showing a landscape view of the camera app on the screen mirroring Apple TV.

Is there a special trick to get this to work with the camera app?

Thank you.
