How to restore or replace a Release Android certificate?

Question

Android

Hello everyone, maybe someone faced a problem, we have not updated the application for a long time and encountered a problem during the update.

We don't have access to the old certificate as the entire team has changed laptops over the past year. Is there a way to update the application?

Answer 1

Perhaps now something has changed, but a couple of years ago, an application signed with a new certificate was perceived only as a new application and nothing else. You can restore the certificate only from your backups, no one else stores it anywhere
