Okay so the AOR is the acknowledgement of receipt, normally the first stage where IRCC contacts you saying your file has been received and a case file number provided for tracking.
In short, I doubt you would be able to link when you haven't yet received AOR as an application number would be required for reference at most of the stages. And this would be sent to you via email when they open your file.
I really don't know long your file has been on their side. But if it's longer that say 3 months you can message them via a webform. Or direct email to inquire as you are worried and they might reply you with an application number, AOR or more information.
Infact mine took me 7 months to get my 1st response and I don't know why. Response though was only after I contacted them via webform so you could do same.
As for the website it's normally general info so don't take word for word always. Eg. On their website they completing files as of Nov 2019, whiles we have 2021 applicant also receiving PPR as in completed processing.
