If your app still appears in the Upload Received state for more than 24 hours after you submit it, there could be an issue with your binary. Contact iTunes Connect Support for assistance by going to the Contact Us section of iTunes Connect. Select Manage Your Applications > Upload Received, then provide the information requested.
We’ve added two new status indicators to iTunes Connect: “Upload Received” and “Invalid Binary.” These new statuses give you a more precise indication of the state of your app when you submit your binary through Application Loader. Upload Received means that your binary has been received through Application Loader but has not yet completed processing into the iTunes system. Invalid Binary means that your binary has been received through Application Loader but did not meet the requirements of iTunes Connect. For more information, refer to the App Store Resource Center , App Store Approval Process section.
