onNotification() not called when app is inactive (not killed) Android

I am using FCM as my remote notification server. Sending notifications hits the onNotification() callback in these two scenarios:

• the app is in the foreground, ie: I am using the app and its taking the whole of my screen
• the app is “killed”, ie: I have swiped up and the app is no longer available in recent apps.

The onNotification() is not hit in this scenario:

• the app is running, but I have switched to WhatsApp (or any app). The notification is received. Upon tapping the notification the app is brought into focus but the onNotification() callback is not hit.

It appears that the app restarts rather than just bringing the app into focus. The app performs as expected when switching between other apps, it’s only interacting with the notification that appears to trigger this restart.

This issue sounds related to #972 but the solution suggested does not work for me.

Closing issues - switched to using https://rnfirebase.io/, would suggest if you are reading this, you do too.

@kashifaliquazi I ended up dropping this package in the end. Moved to React-Native-Firebase and everything worked straight away. Documentation and features are miles ahead. Would recommend you do the same if you can.
