Guys, I received the email from IRCC asking last landing data and email for PR confirmation portal. I replied to it and at the same time, I registered on the PR confirmation portal myself by clicking create account
https://prson-srpel.apps.cic.gc.ca/en/login . I waited for the credentials from IRCC at the same time, but I did not receive my credentials from IRCC even after a week, called IRCC but no information from them .. I was disappointed and then I just simply logged into the portal and to my surprise I was able to see my application on it . Which i then updated my photo and address immediately ...i got my ecopr today a week later ... this was my scenario .. Not sure if this will help you guys .. it's up to you if wanna give this method a try
