Seems like there’s a bug that prevents you from force closing an app while on a phone call in iOS 11.2 Beta 2. Can anyone else confirm that it’s happening on other phones too?
Receive call, swipe up and hold. Hold an app to bring up the red minus icon. Neither clicking on the close button or swiping up close the app.
