iOS App icon is UE4 logo in App Switcher

I’ve set all possible icons to custom, and they work everywhere (settings, push, home screen etc) except for when I’m looking at open apps - it shows the grey UE4 logo. Is this a bug? If not, how do I fix it?

Same issue here. We replaced the UE4 Engine Icons altogether, no change. Looking for an answer.
Same issue seems to have been reported here as well: How to change app icon in ios control center - Mobile - Unreal Engine Forums - on iPad the control center shows opened apps.
