Fullscreen on iPad 2020

Mintonist

Apple iPad Air (2020) has 2360x1640 screen size.
Starling.current.nativeStage.fullScreenWidth/fullScreenHeight are 2048x1536

<initialWindow>
      <fullScreen>true</fullScreen>
</initialWindow>

As a result:

Any ideas how to use all screen without black top and bottom areas?

Are you using a LaunchScreen.storyboardc (generated in Xcode or elsewhere) and packaging it with your iOS app? I believe any iOS apps will default to "standard" iPad size if you don't have that Launch Screen included (and 2048x1536 is normal Retina resolution at the old iPad ratio).

When a Launch Screen is present, the device should pick up on it and use the correct resolution for that device then. At least any version of AIR that's built with the iOS 15 SDK should support all modern device resolutions when the Launch Screen is packaged with it.
