So are you not seeing the email notifications at all, or there's just no option to mark them as read?

The standard e-mail notifications appear, but there is no option to "Mark read", or "Archive" from the notification panel. When it works, you can just click those to mark them read or archive them, without opening your e-mail client. Without them, touching the notification opens your e-mail client and displays the e-mail. If you clear everything, then they all come back whenever you get a new notification. Opening the e-mail client to view the e-mail, instead of just marking it read, is a much slower process.
