My submission is stuck at “Prepare for submission”.I inadvertently uploaded a build created with XCode 7.1 beta. Therefore, if I try to Submit for Review in iTunes Connect I get an error message stating that the app cannot be uploaded with a beta version of the SDK. So I prepared a new buildusing the current version of Xcode and try to upload. But the upload in XCode failed with the error “ERROR ITMS-4238:Redundant Binary Upload. There already exists a binary upload with build version ‘2.1’ for train ‘2.1’” at SoftwareAssets/PreReleaseSoftwareAsset”.iTunes Connect does not give me the option to delete the uploaded build. And the + sign under My Apps in iTunes Connect does not allow me to create a new version. If I anyway attempt to upload a newer version from XCode, iTunes Connect sees the uploaded version but doesn't five me the option to submit it for review. Therefore, my submission process is completely stuck. Any advice?
