Certificate mismatch in play store

I developed a ionic app in V3 and deployed to Google Play Store using steps at https://ionicframework.com/docs/v3/intro/deploying/ Today i needed to release update to the app, i followed same steps and tried to upload. I uploaded the signed APK in play store but it given me an error message that “You uploaded an APK that is not signed with the upload certificate. You must use the same certificate.” After google and all, i found that i have to use that same .JKS file to sign the App however i don’t have access to that computer anymore and this file is not with me anymore.

How can i release an update, can anyone please guide and help?


As far as I know, if you lose your android signing certificate, you won’t be allowed to update your apk in Google Play. You might want to try contacting Google support to see if this is still the case. In the future, I would recommend backing up your certificate somewhere else like Drive. Hindsight is always 20/20 though.
