This issue is likely caused by the aspect ratio of the iPad Pro being different from that of the iPhones and Android phones you have tested on. To fix this, you will need to adjust the aspect ratio settings in your game to ensure that the screen is properly scaled for the iPad Pro’s display.
One way to do this would be to use the “safe zone” feature in the Unreal Engine to create a visible area that is consistent across different aspect ratios. Another option would be to use the “letterbox” feature, which will add black bars to the top and bottom of the screen on devices with a different aspect ratio.
You can also use the Unreal Engine’s “Fullscreen Mode” settings to adjust the scaling of your game’s UI and 3D content. You can use the “Stretch” option to scale the game to the full screen, or the “Letterbox” option to add black bars to the top and bottom of the screen.
Additionally, you can check the resolution settings in your project settings and make sure they are set to support the resolution of the iPad Pro.
It is also important to test your game on different aspect ratios and devices to ensure that it looks and functions correctly.
