This means they have not entered your information into the system. There are different views on this but I believe it could mean, (i) either your package has not been opened, or (ii) your information/docs are being initially reviewed for completeness/errors before entering to the system.
When was your package delivered?
Mine was delivered July 15th and I have not received AOR. The Ecas also doesn't show anything.
