We have been trying to submit an app to the iTunes store using Application Loader for three days and keep getting stuck at the "Authenticating with the iTunes store" step. We have read many forums and tried what was suggested: making a new provisioning profile, using different or multiple versions of Application Loader, changing proxy settings, rebooting the Mac, uploading at a different time of the day, etc. We have even
left it running overnight and have not had success with getting past this step. Unfortunately, no feedback is given about what the issue may be, and we have not gotten any error messages. We have submitted multiple apps without any difficulty in the past but are completely stuck this time! We also tried building the app with the newest Corona Public Build, and it did not help. Has anyone else run into this issue? How were you able to solve it?
