iOS Question Safe Area and white bar on bottom of screen on iPhone 12 Pro

Hi,
I'm facing visualization problems of my app on newest iPhones probably due to an incorrect handling of the safe area.

First of all the app is the same and it is translated in different languages in particular: Italian (first image) and Deutsch (second and third image).

The first image is a screenshot from an iPhone 6S Plus and all the graphical elements are shown and this is the correct visualization.



The second image is a screenshot from an iPhone 12 Pro



In pg_resize I'm using the following instruction
pnlRoot.SetLayoutAnimated(0, 1, 0, 0, Width, Height - r.Bottom - r.Top)


The third image is a screenshot from an iPhone Pro



In pg_resize I'm using the following instruction:
pnlRoot.SetLayoutAnimated(0, 1, r.Left, r.Top, Width - r.Right - r.Left, Height - r.Bottom - r.Top)

The same wrong appearance is shown also on iPhone 11.

I need to block the displaying of the white bar on the center of the screen in the bottom part because it overlaps and hides the graphical elements of the app.

Do you know how to elimate or not allow the comparison of the white bar?

Best Regards.
