I finally decided to update my 640 to Windows mobile 10. But there are two features that are not working and I can�t tell if I missed something. Cortana works when I do a search, however she is no longer notifying me audibly when I have a new text message and asking if I want her to read it. Also I am not getting audio notifications when I get e-mails. I even changed the notification sound since the default doesn�t work, but still no notifications. Am I missing something or are these features gone in the new OS?
