I've been using the Google Mail app without any problem since I've had my GN2. New emails would always show up as notifications. Recently I stopped getting notifications of any new emails. Now whenever I open the Google Mail I notice that it had not refreshed (checked for new messages) since the last time I launched the app and manually refreshed messages. I went into settings for the app and noticed that "Sync Gmail" is unchecked for my account. I cannot find any other setting anywhere else that would seem related to my situation. The weird thing is I don't remember ever explicitly turning this off. Is this my problem? Should I check it?
