We need trouble shooting help. Version 1 of our app is in the Google play store but we didn't save the cert. We created a new app which we want to be version 1 upgrade but when we upload, google play is giving us a certificate mismatch error.
We have the following:
Version 1 apk
Version 2 apk
Is there anything you can do to correct this problem and help us upload version 2 to the google play store?
