Answer 2

What worked for me:

Upgrading, not only firebase-messaging, but all Firebase libraries to the last version. In android/app/build.gradle:

dependencies {
    implementation "com.google.firebase:firebase-core:16.0.0"  // upgraded
    implementation "com.google.firebase:firebase-analytics:16.0.0"  // upgraded
    implementation 'com.google.firebase:firebase-messaging:17.3.4'  // upgraded

    // ...

    implementation "com.google.firebase:firebase-invites:16.0.0"  // upgraded

    // ...
}

Not all of them are at version 17.x
