Firebase App Distribution emails not sent to testers

Question

We have been using Firebase App Distribution for a while now, via Fastlane plugin:

fastlane-plugin-firebase_app_distribution 0.2.3
fastlane version 2.160.0

Uploading the build in the Fastfile:

      firebase_app_distribution(
        app: "{app_id}",
        groups: "{testers}",
        release_notes: notes
      )  

Normally when uploading a new app build to firebase, an email would be sent to all testers. This stopped working a few days ago. No emails are sent.

Manually inviting testers to a build via Firebase Console yields the same result. No emails.

Has anyone encountered this issue? Is it a known (new) Firebase platform issue?

Any news? I've only experience this problem when using gradle plugin, Firebase Console it's ok. – Krugersdorp
