Hello! There is issue with iOS 14.6 and CallKit. Steps to reproduce:
- Fresh install app for identification numbers, reload extension and provide full list of numbers. All is fine
- Reload extension CXCallDirectoryExtensionContext .isIncremental == true - add 1 new number.
Result: All previous phones from first step will be removed, and only 1 number, which we added from second step will be persist
