I just landed in Canada two days ago. CBSA agent gave me a paper which had a web link to upload new address details for PR card. I am logging in with my details but it says:
"We were not able to identify you using the information you provided."
Hi,
Had the same issues, called IRCC many times at the end, you need to go to your express entry account and do link application to your account to track your PR card status
Just fill the paper they gave to you with the delivery address information and fax it to them. I did the same back in July and just got my PR card last week.
