Can someone explain to me how exactly I can sign an App bundle for a new React Native app that I will upload to the Play store? I downloaded the App signing certificate and Upload certificate, but when I upload the Appbundle.aab to the App releases in Playstore it says:
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
How can I create the Keystore with the Upload_certificate.der and how exactly can I sign it?
