Mail notifications aren't up to date
Using Notification center for mail, and the "unread messages" aren't up to date. I have 2 accounts, and in the inbox for one are 3 messages, 1 in the other. However, in Notification Center, there is what appears to be a random selection of messages, some of which are actually unread and unseen, some of which are both read and seen, and some of which are unread but seen.
What I WANT is for it to show all the unread messages in my inboxes...seen or unseen, and ONLY unread messages.
Any thoughts?
