Ionic-native/firebase-x plugin do not trigger callbacks

[fascox]

Firebase Cloud Message notification work quite well under Android. But in iOS notifications are pushed but shows only in Xcode console, callbacks like onMessageReceived() or with getToken() never get triggered.

Related code:

This method never get triggered.

    this.firebase.onMessageReceived() <----
      .subscribe(msg => {
        console.log('message received: ', msg.body);
        if (this.platform.is('ios')) {
          this.toastService.showAlert(msg.aps.alert);
        } else {
          this.toastService.showAlert(msg.body);
        }
      });

Xcode Output console while FCM push message correctly
