Good question, If you have the "proof of your Virtual Landing before", or you have recently "landing", I think they won't send anything to your portal account.
For me, I do check regularly on my ECAS because my representative has my GCkey account. If your ECAS doesn't change to complete. I think IRCC hasn't sent the COPR to you yet. All you can do is wait a few more days. (Usually, ppl gets their E-COPR within 1 day to 2 weeks normally, the longest I have seen is 2 months.)
Another suggestion will be contacting the officer who sent you the first email because I saw someone get their golden email from them, even before the officer had created their accounts. But I think there is a risk that if you bug the officer a lot, they might just ignore your emails, or treat them as spam emails.
