I implement callKit in to app.
Build it with xcode 10.3
Sometimes it happens that the incoming call is hidden.
Only for iOS13.
In iOS 12, the callkit flashes, but then appears.
Application was not closed by system.
And ringing continues to play.
Double click on the home button to open CallKit screen.
How to debug it?
Is it possible that this is a CallKit error?
