<p>Though I don’t know what was in the email, I think that they are less concerned with the supporting credentials being exactly on time than the electronic application. I’d check and see what that email says, and just send them as soon as you can in either case. You might want to send an email if they’re going to be significantly late, but I doubt that it will actually be a “crisis.”</p>
<p>Good luck! :)</p>
