TestFlight'd app on iPad...landscape didn't get prohibited

I’m running test flight on a simple, first app.

I set Xcode to allow iphone / iPad.
I set Xcode to allow portrait and upside down.

I’m testing it on an iPhone 8, iPhone 11, and iPad (not sure the gen of it).

The iPad is allowing it to landscape mode (which affects some functionality).

Can anyone say why it’s allowing it to rotate to landscape when I un-checked the box under project General for landscape?
