Can anyone confirm if the webOS App Catalog submission process still works?

I attempted to publish an update to my app, and when uploading the ipk, was first told the package was "invalid". I then re-uploaded it again, and now continue to get an error that "There is another application in our system with the same application id. Please update your application id and resubmit."

Has anyone else run into these issues?
Are others able to get updates to existing apps published?

I emailed PDC about it and got a reply a week later they were investigating, but another week later, no resolution yet.
