One of our listserv members reports, A Filer uses "Uploaded ADS" and uploads the ADS and uploads all of the other documents for a new patent application. Filer then discovers there is a mistake in the ADS. Filer goes back to the front of the filing screens. Filer clicks to delete the ADS. Filer gets a warning: Removing this application data sheet will result in all previously entered bibliographic data being removed. Filer clicks the red Delete button anyway. And waits... and waits... and waits... Nope, nothing happens. Apparently there is no way to remove the ADS once uploaded. Canceling the submission and restarting is the only way to get out of that loop.
