Answer 1

Found some info in the Angularfire2 docs

Looks like the issue is with the default Angular service worker not supporting the AngularFirebaseMessaging.

AngularFireMessaging is not compatible with the Angular Service Worker

If you are using the Angular Service Worker, you are not currently able to use AngularFireMessaging. If you'd like this feature please file an issue in either repository. Your alternatives are to use WorkboxJS or just simply use the Firebase Messaging Service Worker, which is detailed below
