Are there others here whose applications were received before May 6 and don't have their applications in process?
I am. Mine is on received status.
 
I tried ECAS using the receipt number (receipt number of the fees paid as I just had that nothing else) but I think its not available for me yet. It says no info found.

If you already have AOR try with your UCI Number which is equal to your PR card number as well

Good Luck
