Can not upload apk on playstore second time

I have uploaded apk file few days back on playstore. after that I deleted my keystore and couldn’t update that app again. Now I am trying to upload new app but playstore giving error

I tried to change package name in config.xlm but still not working?

what could be the issue playstore don’t allow to delete previous app

So i guess you are using Cordova? When you cange the Package Id, try removing the platforms Folder and build the App again
