This will be the fifth bug I have found in Apple's code in two weeks that is preventing me from distributing my app.
I cannot reply to the reviewer who reviewed my app. Why? Another unspecified error. What did I do wrong? I attached a screenshot. Then nothing happened. So I tried to attach it again. Then I tried to remove the second attachment. Then I got this error.
The level of pervasive flaws in Apple's systems is really unacceptable.
