IOS 15 facetime - missing center stage

For iPadOS15, Centre Stage settings are accessed from the Control Centre whilst a supported App is running. Swipe downwards from top-right of the screen:

Be aware that Centre Stage is only supported by 2021 models of iPad Pro, the iPad9 and iPad mini6.

CenterStage can, also, be activated in the Control Centre drop down in the upper right hand corner of the iPad’s screen.

I find it can be set up when you open face time. I can’t see it in settings either.

I too cannot access center stage, either in FaceTime or control panel settings.

I have the iPad Pro 12.9” 4th gen Wi-Fi model
