I have just tried switching from Fabric/Crashlytics Beta to Firebase App Distribution for distributing my Android app to testers. I do so using the Gradle plugin as described here: https://firebase.google.com/docs/app-distribution/android/distribute-gradle
When using Crashlytics Beta, I could disable the annoying emails to testers for every new build by adding this to my gradle file:
ext.betaDistributionNotifications=false
The docs for Firebase app distribution don't mention anything similar, despite having equivalents for the other options such as release notes. Indeed, the doc says:
Testers who haven't been invited to test the app receive email invitations to get started. Existing testers receive email notifications that a new build is ready to test.
Does anyone know how I can disable the emails so that I don't constantly spam my testers when I push out builds several times a day?
Edit: Individual testers can use the unsubscribe link at the bottom of the emails, but I'd prefer to disable the emails globally so that this isn't necessary.
