We built an app for Android 3 years ago. We need to submit the update to the app, but we don't have the private key that was used in the original app (the one that we're updating. Our original developer is nowhere to be found).
How can we get around this?! I don't want to submit the app through a separate developer account and I really need this new version to be accessible to the thousands of people who have downloaded version 1.0.
Anything you can do to help would be appreciated SA compadres.
Thanks in advance for your help.
