All of your Google Play apps have been successfully registered

There was an email from Google saying that Android apps in the Play store (and outside) need to be registered, and we need to register keys if we are signing outside the Play Store.

One of our apps was being signed outside the Play Store, so in the URL

play.google.com/console/u/6/developers/android-developer-verification

clicking the arrow against that app, it asks us to add the public key.

To find the public key,

https://support.google.com/googleplay/android-developer/answer/16641489

where I'm using this method in a github action,

      - name: Extract SHA-256 fingerprint only

        run: |

          BUILD_TOOLS="$ANDROID_HOME/build-tools/34.0.0"

          "$BUILD_TOOLS/apksigner" verify --print-certs app-release.apk \

            | grep -i "SHA-256"

I clicked on Add Key and added the digest, at first it showed Pending verification, in 10 minutes it showed verified.

Here is part of Gemini's reply on why this key is needed - 

To ensure your app functions flawlessly whether it is downloaded from the Play Store, sideloaded by a QA tester, or downloaded directly from your website, your backend services (Firebase, Google Cloud, etc.) should always have both fingerprints registered:

1. The Google Play App Signing SHA-256 (found in Play Console -> Release > Setup > App Integrity).
2. Your Local Keystore SHA-256 (the one generated from yourkey.keystore).
