A number of users appear to be having problems with some apps crashing on launch following updates downloaded from the App Store. Instapaper developer Marco Arment reports that “within minutes of Apple approving the Instapaper 4.2.3 update” last night, he was “deluged by support email and Twitter messages” from users indicating the the app was crashing on launch, even with a clean install. Arment notes that not only had Apple obviously reviewed the app, but that his own submitted version worked fine, yet when he downloaded the update himself it “crashed instantly.”
Arment goes on to report that in some regions the App Store is sending out a “seemingly corrupt update” with the U.S. and U.K. being specifically affected, but not Australia as far as he was able to tell. Developer Ken Seto of Massive Damage notes that the issue may be affecting some Canadian users as well. Arment lists several apps that have been reported to him as causing issues, including his own Instapaper app along with GoodReader, Readdle Scanner Pro, Threadnote, Please Stay Calm, Angry Birds Space HD Free and more and notes that he contacted App Review very shortly after the Instapaper update went live and it appears that a functional version of Instapaper began being distributed on reinstalls and doesn’t appear to have recurred since. Users who are experiencing a problem with newly downloaded apps crashing due to corruption will likely need to wait until a good copy is being served again by the App Store, and then delete and reinstall the app.
