Question: After an errorfree validation from AppStore I’m getting errors of “Apple’s web service operation was not successful” and “Exception occurred when creating MZContentProviderUpload for provider. (1004)” from Apple when I am trying to submit my iOS 5 app to the store by Xcode 4.4. What’s wrong? Have you ever got such an error message? Answer:

Yes. We had no binary error when this message was received. Try to upload the same binary an hour or so later. I guess there was another temporary issue with Apple’s server today morning.
