Had the same problem. I am using FCM with Firebase-admin sdk on nodejs.

Fixed it by adding a tag to the payload. const payload = { notification: { title: "New notification, body: "Body", tag: "RANDOM_STRING_HERE" } };

Brilliant, works for me now thanks.

For anyone else coming up against it, I needed to keep the receiver in my AndroidManifest and add the tag to my notification object as detailed above
