Earlier today, Instapaper developer Marco Arment reported that the App Store is pushing out corrupt binaries that cause a crash on app launch.
Apple has now responded to complaints in its Developer Forums with a brief statement posted by username 'iTunesConnect'.
"We are aware of the issue related to apps crashing after update. We are currently working on resolving the issue. Stay tuned for updates."
App developers are recommended to hold off on submitting applications to the App Store until this issue is resolved.
