I made an app for calls with CallKit and PushKit. It seems everything is done correctly, according to apples manual on CallKit and PushKit. If I start app on two devices, and try to make a call everything is working for the first time, and it can work for the second time and so on. But then, by unknown reason (I don't handle any errors), the phone that receives voip push notification ringing but doesn't show the panel with answer/decline buttons. If that happens, new incoming calls work the same broken way.
To improve that broken situation I must initiate outgoing call with CallKit on broken phone.
I don't post any code, it just the same as in numerous examples.
Do anyone has guess what's wrong?
