Is the AP Mobile news app crashing on your Windows Phone 7 based HTC smartphone after the NoDo upgrade? AP is aware of the problem and posted a note to the AP Mobile blog.
AP has narrowed the problem down to HTC phones updated to OS version 7.0.7390.0. My HTC HD7 meets both these criteria and is experiencing these crashes. The AP Mobile app starts up on my HD& and even allows for a few seconds of navigation before crashing back to the Windows Phone shell.
AP says they expect to release an update in a week or two to address this problem.
