Google Auth (Sign-in) doesn't work after deploying to 'Internal Channel' at Play Store

Hi all!

Normally, when i was testing the app, i downloaded the apk, and run this code "keytool -printcert -jarfile myapp.apk" to obtain the SHA-1 key, that i've been placing on Firebase to be able to sign-in and login. After that, i just installed the APK on my phone, and i was able to login without problems.

Now i deployed my app for the first time to Play Store, i thought that FlutterFlow would sign and add the SHA1 to Firebase config, but seems not. I have to do something manually to get the app on the internal track be able to login??

Thanks.
