I am submitting an iOS app to the App Store using Application Loader, however, it never gets past the "Sending API usage to iTunes Connect" stage. There is no error - this stage just doesn't complete.
I have verified that the Mac is connecting to the internet (I can visit websites). Also, the app is tiny (6MB) so this can't conceivably just be a long upload. I've tried leaving this for 20 minutes.
The background to this is that I developed in Flash CS5 on a Windows PC, built it for distribution there, and now on the Mac I am loading the final file into Application Loader to submit it. It verifies/validates the file just fine, but won't go beyond this point.
Any ideas anyone? Perhaps it's a network issue?
