I was able to get a co-worker to help me with this - a head-scratching different order of button clicks got us past this issue. But when I attempt to publish, I get the following error message:
Failed to Publish application. Unexpected error: NoPanelsDefined
My app is not an installable app, so I'm not sure why I need any Panels defined?
My app id is 113191.
I would really appreciate any help you can provide.
