I need to know how to get this to work also. A previous build was uploaded to the app store in an older version of UE4. But now the system has changed and I cannot upload a new build via Application Loader as the new build system gives a 0.xxx number which is lower than the previous submissions build number.
So I literally cannot submit a new build for my game in order to get it on the app store…
