Same thing happened to our case. Our passport + photo and document request letter were received on Jun 02 by CPC Ottawa. today I got all things mailed back without CoPR, plus one letter with same reply as yours -- "...We will contact you with information on confirming your status as a permanent resident ..." . I checked the xpresspost tracking information, this mail was sent out yesterday (Jun 10)
Just checked online accounts status, it became to Complete and added one line " You entered Canada at the Etobicoke IRCC office on June 10, 2020 and became a Permanent Resident."

-- seems the landing steps is skipped for my case.
