I developed an app using Xamarin.Forms, and I would publish the app to Google Play Store, I generated the APK and Store key as the following document (https://docs.microsoft.com/en-us/xamarin/android/deploy-test/release-prep/?tabs=windows) from Visual Studio, but when I upload the APK file to Google Play Store, I get the following error.
Upload failed You uploaded an APK that is not signed with upload certificate. You must use the same certificate. The Upload certificate has fingerprint...etc
I have the old KeyStore but I lost the keyPassword
