I have enabled "Google Play App Signing" for the app that already existed on Google play.
Now I cannot upload new app versions with the old KEYSTORE (.keystore) file.
Should I generate a new KEYSTORE file based on certificate fingerprints (attached in the image bellow) and how?
NOTE: This question is specific for the Unity platform. (2018 Release of Unity)
The actual error message I get after the new app version upload is like this:
Upload failed
You uploaded an APK that is not signed with the upload certificate. You must use the same certificate. The upload certificate has fingerprint:
[ SHA1: 9A:... ]
and the certificate used to sign the APK you uploaded have fingerprint:
[ SHA1: 36:... ]
