I'm using Xcode 8 Beta 3 to upload a Messages extension to iTunes Connect. During the upload I can see the app is "being processed" in the All Builds section of iTunes Connect's Activity tab. The moment Xcode finished uploading (Xcode shows an upload successful, thank you for uploading your app the App Store message), the listing of the app in iTunes Connect's Activity tab dissapears. The All Builds screen is empty.
Attempting to upload the same build again using Xcode doesn't work either. Xcode shows an error message a version of the app with the same the version and build number already has been uploaded (which is correct): ERROR ITMS-4238: "Redundant Binary Upload. There already exists a binary upload with build version '4' for train '0.2'" at SoftwareAssets/PreReleaseSoftwareAsset
Has anyone come across this issue?
