I know there are a lot of questions about this already, but I am fairly certain my question has not been answered yet.
I uploaded a build of my iOS app via Application Loader, and that went well. I got to the end with a message of "Done", so I thought it was okay.
Then I went to check in iTunes Connect and I cannot see a build (not even under "Activity"). I waited for an hour and I retried uploading the build. In Application Loader I now get the error "Redundant Binary Upload", so that tells me that my build is somewhere in iTunes Connect, but I can't find it.
What could have gone wrong? Is this something that usually happens? How can I know when my build is "Processing", so I can continue with the release process?
