I am having issues with the stock email app. Even though I have it set to fetch every 15 minutes it will go sometimes for hours before checking. I have verified that it is not set to manual under mail, calendar>fetch new data and I have reset network data. Also I have reset the phone through iTunes on my pc to a "new iPhone" default setting and none of that has worked. Has anyone had this same issue and if so been able to fix it? Thanks
