I have a VoIP application. I implement CallKit in it. I build it in Xcode 10.3
Sometimes it happens that the incoming call is hidden. Only for iOS13. It is not possible to answer the call.
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.
For all call create a new NSUUID with: [NSUUID UUID]
Please can you advise me?
