So just to give you an idea, we applied Outland Paper. We have received SA (Sponsor Approval) last March 28, 2022. Then in ECAS I saw this "We started processing your application on April 19, 2022." Then on April 21, 2022 in GCKey, under Current Status, it says "Application/profile updated". When I logged out and logged in again in GCKey the "Application/profile updated" went back to "Submitted". Since you guys applied online and ECAS is not applicable for Online Applicants, maybe you just need to watch out for GCKey ghost update and probably that is your AOR2. I have read that AOR2 means acknowledgement of you application transferred to local visa office
