P1: May 22, 2024
P2: pending
eCOPR: pending

I called IRCC today at 1-888-242-2100 trying to get a confirmation whether they received my P1 response. The lady could not confirm it as the email goes straight to the office that will setup the login credentials. Also, they don't send a confirmation of receipt anyways, and, if they don't add any notes to your profile in the system, a phone call won't help much.
She said, though, that this is a lengthy process and it could take from a couple of weeks to a couple of months, and if you replied within 7 days to the right address (the same one P1 was sent from), you can rest assured that it is on their queue to be processed.
In summary, a PR process is the best patience/waiting course you can take in the world.
