The Google Console requires registering package names. All my apps registered automatically, except for one new one.

When I click "Register Package," I'm given three eligible public keys to choose from. One of them matches the App Signing Key (SHA-256 certificate fingerprint) that I see in the console's App Signing section. I selected it.

Next, Google asks me to add the adi-registration.properties file to the app, then create a release APK and sign it with the key I selected earlier.

But I sign all my apps with a different key—the Upload Key. After uploading the bundle, Google signs the apps automatically.

Accordingly, when I create an APK signed with my upload key, Google reports "The uploaded APK has a different signature."

How should I proceed?
