why isnt the center stage option available on my new ipad

It seems you need to start a FaceTime Call at least once before the Center stage option appears in Settings.

Just start a call in Facetime and immediately hang up, and the option should appear.

Also…just to be sure…do you have the M1 2021 iPad Pro? If not thrn you won’t have Center Stage. I only ask because some have purchased the 2020 models not realizing that the feature isn’t available for those models.
