Removing old unreleased APK signed with bad keystore

Hi all,

An old APK was uploaded to the STORE release channel, and was not released. The keystore used for this was lost, so now I cannot update the build with the fixed version.

Since the app was never actually released yet, is it possible to delete the old unreleased APK and replace it with a new one? There is surely no technical roadblock in doing this, but I imagine it requires some Oculus backend intervention.

Thanks!
