问题
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

Sorry to tell you the bad news, from the official Android developer docs:
Ensure that the app signing key is not lost. Loss of the app signing key means that an app cannot be updated, so it is critical for it not to be lost.
Update
It seems like Google now allow reseting certificates. Please fill-in an issue on this form. The operation may take a couple of business days.
Thanks @SushiHangover for pointing that out!
