Hi,
Sharing my experience here hoping it might help you guys. My COPR number appeared on the tracker, and my background check was completed, but I didn't receive P1. When I called IRCC, the agent confirmed that P1 had been sent, but I never received it. They advised me to wait, but after two weeks without any updates, I decided to take action.
I sent all the required information for P1 (I assume this is the KAI method?) to the IRCC email and the Etobicoke office, as the call agent informed me that my VO is Etobicoke. A week later, I received P2. I completed the process on the same day and received eCOPR a week later.
