In release mode, the values are missing. I don't know what's wrong with it. If I install the debug version first and then overwrite it with the release build, I can retrieve the values stored in debug mode. But if I uninstall completely and install the release version directly, it's empty

In situations where the app receives a VoIP push, and the user starts to answer by sliding, the call is initiated and the timer starts. However, due to network issues, the app's call may not be fully ready, resulting in a delay of 5-10 seconds before the actual call begins. Is there a way to display a "loading" or "connecting" indicator on the CallKit interface during this wait time?
