Looks like the app is ignoring the native safe areas. This happens for example when you use image catalog instead of storyboard file as splashscreen in the Xcode project, or when you are missing the correct viewport-fit meta tag:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no, minimal-ui, viewport-fit=cover">
