Manually upload .aab file to Google Play Console: On 1st delivery you 1st will get the .aab file from our support team via your onboarding Jira ticket. This is actually will be your app build in .aab format. You need to upload this file to your Google Play Console → inside “Internal testing” track.
Link Firebase and Google Play Console: Once you upload this file there and publish the internal testing track, you will be able to link together your Firebase project and Google Play Console. Without this linking we are unable to deliver the .aab format builds to your Firebase → App distribution which you need for release in Google Play Console.
