We are trying to upload a new version of our app, and need to cancel the current submission. It's been pending for several months, so there's obviously a glitch sometime. We've tried several times to reach out to support. At first we would get clearly cut and pasted replies that failed to even address our questions. Now we don't get any replies at all--just confirmations that our message is received. Are there any tricks to canceling a submission that we don't know about? We've tried canceling it ourself but only get the following message: "We are unable to cancel your submission for this application."
