Yes, because I already have an account in PR portal https://prson-srpel.apps.cic.gc.ca/en/login
After replying an Email within next 2 hours my application was linked with PR portal. Well, still haven't received any email after that. Self declaration, photo & address being reviewed by IRCC.
I also have the PR portal and the application has been linked to my portal and I could do self-declaration and photo upload.
Did you receive the portal credential email or we should not expect to receive that if we already have a PR portal?
I really appreciate your help
