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?
