Starting from the "Manage Your Apps" window in iTunes Connect, click the big icon for your app.
That will bring you to the "App Information" and "Versions" window.
在“版本”部分中,单击“查看详细信息”按钮。
在下一个窗口中,右上角应该有一个按钮,上面写着“上传二进制文件”之类的字样按那个按钮。
There's where you answer about encryption. Answer those questions about encryption and your app should be moved to the Waiting for Upload status.
回到“应用程序信息版本”窗口,在“版本”部分应该显示“等待上传”。
Nowadays you will be informed specifically if you have a Bundle ID mismatch when you try to do the upload from your Xcode organizer. It'll even tell you which Bundle ID you have in iTunes Connect and which Bundle ID your app has.
