The Mac App Store is supposed to make things easier, but it’s also a single point of failure. Not only is it neglected, but sometimes even the existing functionality stops working. Mac OS X 10.9 introduced a code signing bug that prevented me from submitting updates for several months. In June 2015, there was a month-long iTunes Connect bug that prevented my uploaded build from entering the review queue. And I currently have a bug fix update that Apple has been reviewing for 33 days (with 8 days of waiting before that). When I inquired about the status, Apple told me that everything was normal and that I should just keep waiting. In short, the system is broken on multiple levels, and there is no evidence to suggest that things will get better.
Harsh words, but I don’t see how anyone could disagree.
He also has a collection of tweets regarding the App Store’s expired certificate fiasco. The last one made me laugh.
