To resolve this, the following dependency needs to be added to the build.gradle entries to Suffix in the Native -> Android Mobile/Tablet -> Gradle Entries section:
dependencies {
implementation 'com.google.firebase:firebase-iid:21.1.0'
}
If there are already entries for dependencies, only the single implementation line needs to be added.
