I manage to fix it by upgrading these packages to the latest versions:

Firebase Core -> com.google.firebase:firebase-core:16.0.3
Cloud Messaging -> com.google.firebase:firebase-messaging:17.3.0

Unfortunately, updating firebase core and cloud messaging didn't work for me.

When I updated, originally, I got this gradle sync error:

Error:Failed to notify dependency resolution listener.
The library com.google.android.gms:play-services-measurement-base is being requested by various other libraries at [[16.0.2,16.0.2]], but resolves to 16.0.0. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

So updated the node_modules/react-native-firebase/build.gradle to use the latest packages, and that got things compiling.

compileOnly "com.google.android.gms:play-services-base:15.0.1"
  compileOnly "com.google.firebase:firebase-ads:15.0.1"
  compileOnly "com.google.firebase:firebase-auth:16.0.3"
  compileOnly "com.google.firebase:firebase-config:16.0.0"
  compileOnly "com.google.firebase:firebase-core:16.0.3"
  compileOnly "com.google.firebase:firebase-crash:16.2.0"
  compileOnly "com.google.firebase:firebase-database:16.0.2"
  compileOnly "com.google.firebase:firebase-firestore:17.1.0"
  compileOnly "com.google.firebase:firebase-functions:16.1.0"
  compileOnly "com.google.firebase:firebase-invites:16.0.3"
  compileOnly "com.google.firebase:firebase-storage:16.0.2"
  compileOnly "com.google.firebase:firebase-messaging:17.3.2"
  compileOnly "com.google.firebase:firebase-perf:16.1.0"

Not sure if I did something stupid there.

I receive messages fine when the app is in the background or closed. And messages fully work for me on ios, including when the app is open. It's just on android, and if the app is open.
