I've noticed that my S5 isn't removing items from my notification bar that I've already read on my computer. I've noticed it so far with Gmail, Exchange & Hangouts, where if an email comes in and I read it on my computer, it doesn't get removed from my notification bar. It syncs the read status, so if I were to open Gmail it would show the email is read. Is there a way to have the notifications go away once these messages are synced to read status?
