The content feeds that feed the Macworld Daily Reader were recently corrupted accidentally. The problem has been fixed, but once a feed is cached in our app, it can cause the bug to persist.
If you or your friends are seeing frequent crashes in Macworld Daily Reader, please uninstall the app and then re-install it from the App Store.
We're sorry for the inconvenience. We've fixed the bug in our feeds and made a change in the next version of this app so this bug will never recur.
