IONIC v3 android app does not receive FCM notification message sent from Node.js applciation SDK firebase-admin

[haresh333]

Problem - Recipient client app does not receive PUSH notification when sent from my server app I have IONIC v3 mobile app and using @ionic-native/firebase-messaging@4.20.0, cordova-plugin-firebase-messaging@2.1.6 I also have PWA app built from same codebase

Observations

1. When I send message from server to IONIC app, it does not receive - neither in foreground nor background mode
2. When I send message from same server to IONIC PWA app, PWA app receives message.

The server code admin.messaging().send(payload) returns success response with following projects//messages/0:1610460192971479%9edb2772f9fd7ecd

With this I infer in all likelihood there is no issue with Server code

Using debugging, I capture token of the IONIC mobile app getToken().

3. When I send Google Firebase Console to this token if the app is in foreground I do not get the message. 4.When I send Google Firebase Console to this token if the app is in background I DO GET the message. I see this in notification drawer in Mobile. However, I dont think the App get the message (no console message in the console.)

What may be wrong, How do I investigate?

I am using Following application stack

Server (to send FCM push messages) Node v10.22.0 "firebase-admin": "^8.12.1",

What can be meaning of this, is the application not able to catch hold of PUSH ?

@haresh333 by default when app is in foreground only onMessage callback triggered without native notifications. If you need native notifications pass forceShow option into requestPermission call.
