Received the Lollipop update a couple of days ago. Samsung Galaxy S4. E-mail is now buggy. I don't (usually) get the blue light notifying me of received mail. Every now and then it DOES blink. My priority sender list also doesn't notify and doesn't play the specially selected tune to let me know of the high priority mail. The only way I know if I have mail is to access the home screen. Also, the "Inbox" still shows "1" message when the folder has been completely read and cleared.
