The add contact page takes a lot more moves in order to add contacts that you want to add more then just the email address for. There was an option to select add more then one contact on the page that would let the add contact page refresh. Now in order to add another contact you have to go back to contacts, and start all over again. Adding like five contacts takes the time of adding ten compared to the way it was.
