I have successfully built and uploaded a new version of an app with Xcode 7.3.1 in OS X 10.11.5, but the build is not showing in iTunes Connect.
After the build process (launched through the "product->archive" menu) the Organizer opens. There, I choose the build and click on "Upload to App Store..." So far, everything works as expected.
After the upload, when I refresh the iTunes Connect web page (under the "Activity" tab), I briefly see the new build showing in the list. If I refresh the page again, some seconds later, the build has disappeared. I can no longer find it anywhere in the iTunes Connect site. When I try to repeat the process, XCode gives the following error message:
ERROR ITMS-4238: "Redundant Binary Upload. There already exists a binary upload with build version '2.4' for train '1.5'" at SoftwareAssets/PreReleaseSoftwareAsset
so I have to increase the version number to complete another upload.
I went through this process 3 times, the last one using Application Loader instead of XCode, but the same thing happened all the times.
Does anyone know why this is happening?
What could I do to troubleshoot this problem?
What other informations may be useful to further investigate?
UPDATE
More than 48 hours have passed since the first upload, still no signs of any builds in iTunes Connect.
