Hi Daniyal - One from your permanent address should suffice. If you are requested additional PCC, you can submit those later for Islamabad and Abbottabad.
You usually get an update on tracker as "Background verification status has been updated to In progress". At least that was the case for my application.
So far what I have seen, everyone is in security who has been waiting to hear back for a while, everything is completed except background check and had this update in tracker. We can only infer the inner workings of IRCC based on patterns.
I would get the PCC from the last address or permanent address. They can mention the period of stay whatever it is for that address. From what I remember, PCC won't have dates of stay. Btw, I believe only one PCC per country is required.
Unaccompanied would not have solved it. I know cases where unaccompanied spouse security is in progress and causing delay anyway.
This simply means normally processing times don't apply to you. Those are just agent codes that are working on your case. Usually they redact this kind of information.
