Ionic 2 FCM Plugin

Ionic Native
1

I’m implementing Push Notifications on my Android Ionic 2 App with the Ionic Native FCM

When I’m receiving a notification in the foreground it works, but when I’m receiving a notification in the background and if I clicked on it, nothing happens.

firebaseInit(){
  //Firebase
  this.fcm.subscribeToTopic('all');

  this.fcm.getToken()
    .then(token => {
      console.log(token);
      this.nativeStorage.setItem('fcm-token', token);
  });

  this.fcm.onNotification().subscribe(
    data => {
      console.log("NOTIF DATA: " + JSON.stringify(data));
      if(data.wasTapped){
        this.nav.push(MemoViewPage, {memo: {_id: data.memo_id}})
        console.info('Received in bg')
      }else{
        let alert = this.alertCtrl.create({
          title: data.subject,
          message: "New memorandum",
          buttons: [
            {
              text: 'Ignore',
              role: 'cancel'
            },
            {
              text: 'View',
              handler: () => {
                this.nav.push(MemoViewPage, {memo: {_id: data.memo_id}})
              }
            }
          ]
        });

        alert.present();
        console.info('Received in fg')
      }
  });

  this.fcm.onTokenRefresh()
    .subscribe(token => {
      console.log(token);
  })
}

The if(data.wasTapped) condition doesn’t go off once I clicked the notification from the system tray.
