react-native-fcm: Remote notification is empty when I call FCM.getInitialNotification

I am using react-native-fcm ^6.0.2, react native 0.41.2 on an android device.

This is the scenario:

In my app I have a class named LoadingScreen. This class is just waiting for a push notification to change to the next scene “FinalScreen”. When the app is visible (foreground), if I send a push using the fcm console, the app receive that push and everything works perfect. The problem is: if the app goes to sleep or goes to second plane, when I send the push, the device show me the push in the notifications area, but when I clicked in it, the app shows me the LoadingScreen and nothing happens. The “notif” object is almost empty. If I do something like notif.fcm(in the js console), it only contains the action key.

This is the code of the LoadingScreen.

componentDidMount() {
    _this     = this;
    prevState = this.props.prevState;
    
    //Set some stuff
    this.setState(this.state);

    this.notificationListener = FCM.on(FCMEvent.Notification, async (notif) => {
      
      if(notif.fcm.body !== undefined){
        Vibration.vibrate();
        Actions.chargeFinalStep({prevState: _this.state});  
      }    
    });

    FCM.getInitialNotification().then((notif)=>{
      console.log("FCM.getInitialNotification");
      console.log(notif)
    });

    this.refreshTokenListener = FCM.on(FCMEvent.RefreshToken, (token) => {
        console.log(token)
        // fcm token may not be available on first load, catch it here
    });
    }

Any help would be appreciated 😃
