Doesn't work in Android Release mode

[hmziqrs]

Hi, I've been trying to debug the issue but didn't have any success. No authentication-related method works in Android release mode but works fine in Android (Debug) and iOS (Release and Debug). I've combed through the docs a few times but didn't see any Android related configuration I might've missed. I've also tried to build release APK from 2 MacBooks and 1 Window device.

Issue:
Async methods are not resolved or rejected they are stuck at loading.

Here's the demo app where you can test it:

@Ariflo Thank you. Add progard-rules fixed the issue. But please make this part of the documentation as well.
