Recently Apple's app store has been criticized by both ordinary users and app developers. Problems arose when installing and updating applications. According to the cnet.com portal with reference to the founder of the Instpaper service Marco Arment, users who installed Instapaper 4.2.3 from the App Store could not properly launch the updated version of the popular application.

The problem remained even after the complete uninstallation of the utility. According to the developer, the technical support mail was "attacked" by messages from disgruntled users in just a few minutes.
Marco Armenta is sure that the application assembly did not have such bugs when sent to Apple. Instapaper reacted immediately and sent information about the problem to Apple engineers. The problem was fixed within a few hours. However, according to Marco, the encryption error affected several other applications.
Users of 20 other applications for iOS and Mac encountered similar errors. Marco's words were also confirmed by The Verge portal, citing their sources. PDX Bus programs, as well as the popular Angry Birds Space HD, Pinball Maniacs and GoodReader, were noticed with errors. In the case of these applications, only a complete reinstallation from another source resolved the problems.
According to some reports, the GoodReader development team reports that users may still encounter errors in the operation of some applications after updating. Strange as it may seem, but no official Apple comments about what happened have appeared in the media.
