iPhoneX does not close Unreal Engine Game

Swapping up for closing apps on iPhoneX does not work for Unreal Engine Build Games, I have to restart the phone to close the app. Is there a solution yet for this. I’m using Unreal Engine 4.18.2.

Swapping and closing our UE4 game on iPhone X works without problems. The big thing missing for us is full screen support. Also, it seems that there is some confusion in screen coordinates for hud elements. They are being drawn to a weird x,y offset.
