Hello,
I have an app from few years ago that needed to be updated due to last year google requirements. Initially the app was build via android studio. Now to rebuild the app and publish a new release I used backoffice Service APK generator. When I uploaded the aab file I got the following error:
Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key and try again. Your App Bundle is expected to be signed with the certificate with fingerprint:
I understand what it means but I am not sure how to proceed. Where do I get the old key and how do build the new app version with the old key.
Any help is much appreciated.
Thanks
Alex
