Email app will not open
When I select the email app it tries to open, showing the mail page format but unpopulated for a few seconds and then returns to the home page. I have tried powering it off and back on, doing a reset, removing apps from the taskbar, and deleting and reinstalling mail accounts but still no luck. Any other suggestions? This only appears to have happened after I installed the recent software update but I have no idea if it's connected to that.
