Hi! I've setup my app for push notifications through Firebase (only Android app, for now).
All the configuration is done: the FCM legacy key is set up, the user is subscribed for push notifications, the user's device ID for notifications (in the App42 console) is the token received from Firebase, etc.
When sending push notifications from the Firebase console, everything's working perfectly. The problem is that notifications sent via App42 (either from the console OR from code) are never shown. When the app is opened, Firebase shows me that I got a new message, but there is no notification attached to it (I assume this could be the problem).
What am I doing wrong, please advise.
