Ok thanks for your response.yes, I got AOR June 7th. and I created tracking account on the 9th. so its already in progress.

So as I understand, the fact that you were able to create an account using your UCI & Application No in the above link means that ECAS is in progress.
No other email or updates were seen to conclude that ECAS is in progress.
