My parents PR decision was made on Dec 04 2021. It took more than 6 weeks for them to send me first portal email requesting to provide few details. I called them few times to inquire about the application. Each time they gave me different answers.
I would say just wait for couple of days. My friend got his username and password for Portal login in few days as well.
Dis you get automatic reply after submitting those details?
Also with the attached PDF, it says that If you can’t access online tools such as the portal, or if you experience any technical issues with the portal, please let us know by replying to:
IRCC.ClientPortal-PortailClient.IRCC@cic.gc.ca
I hope you get that email ASAP.
