FCM: notification gets to the device, getting warning messaging_notification_received with no listeners registered.

[DavideValdo]

Testing out FCM from the Notifications panel in Firebase.
Notification is delivered to my iPhone, but all I'm getting is that warning.

This logs the message object correctly:

    firebase.messaging().onMessage((message) => {
      console.debug(message);
    })

Any hints?

react-native-cli: 2.0.1
react-native: 0.45.1
yarn: v0.24.5
react-native-firebase: 2.0.0
XCode: 8.3.3
iOS 10.3.2

What you mentioned makes sense with what I described in issue #204

Thank you.
I did try your workaround, but it seems like it's a different problem.
I now get an additional message in console from infoLog.js:

After a clean install, I can get the alert when app is in the background.
For Android, I was expecting to get the alert automatically when app is in the foreground as well.
Is not showing the alert expected behavior?

@DavideValdo the notification wont show when the app is open, which is intended. Currently there's a work around in place by putting show_in_foreground: true in the payload.

[DavideValdo]

Current status:

1. Local notifications with show_in_foreground work only on Android, on iOS i still get 'messaging_notification_received' with no listeners registered warning, even if the app is in background. *Anybody had better luck with this?
2. Remote notifications working with app in background both iOS and Android, but show_in_foreground is just ignored on both platforms when testing via cURL

Seems like a different issue anyway, closing this and opened #223
