I am having trouble getting my e-mail to sync ever since I updated to the latest version of the software. When I go into accounts in the settings menu all of my apps have sync disabled and it is greyed out, will not let me enable any of them. Normally when I pull down the notification bar there is an option to enable or disable sync, however since I upgraded to the newest version of the software this option is no longer available. Is there another way from the settings to re-enable sync?
