I hear you, pre-arrival was on July 26th, and SA and AIP was on August 1st....nothing after that, eligibility was and is still saying We are reviewing whether you meet the eligibility requirements. HUH you already sent me my AIP so thought you had finished with my eligibility. LOL Background was saying your application is in process, but now that I have the FD, background now shows We are processing your background check. We will send you a message if we need more information. This is on GCKey. Their system is not perfect in any way, but at least it gets us to the final destination. Tracker showed yesterday that background was completed along with the COPR details.
Our application started out a bit weird anyhow. People who had submitted around the same time were commenting that they had received AOR a few days to a couple of weeks after the submission. I received BIL the end of April, and MIL the first week of May. Still no AOR, so I was concerned, knowing that it was supposed to go to the sponsors email, did that get input on the application correctly? So I did contact IRCC via phone and webform to double check and to state we hadn't received the AOR, they said email was correct, and they sent the AOR to us on May 29th. Who knows maybe we were ones that weren't slated for the AOR. LOL Anyhow, things went "smoothly" after that. Lots of waiting and lots of patience needed, but getting these last few updates is well worth the wait.
