AOR2 is the acknowledgement that the visa office to which your application has been transferred, has received your application.
So, now in your case, wait for AOR2 email. It doesn't take more than a week to receive that email.
It is been around month I didn't receive any further email.
This is what I received 3 weeks ago and no further email after that.
