Kill the app and receiving call not working

Hi,
When I kill the deviceA and call from deviceB, Am getting call in deviceA as CallKit UI. when I accept it call failed. Looks like session become invalid once we kill the app. Please help on this how to maintain it.

Hello.
Could you check authenticate(params:completionHandler:) is called and succeed before accept.

Hi I fixed it by authenticate in didreceiveincoming call. Thank you
