@LeighBrown Hello. I am uncertain how to actually set up the e-portfolio account manually, but for me, I happened upon a link that went directly to the portfolio account from Canvas. It might be that my university did it for me without my knowing, or it could be an automatic function of a new Canvas account. Try looking there.
Your Canvas setup may be totally different than mine, but I will try to walk you through where the link was for me.
After logging into Canvas, my display shows a link to my account on the left side. Clicking that provides links to Notifications, Profile, Files, Settings, and for me Folio. It is the Folio link that took me to my e-portfolio link. I first had to do a quick setup with my personal information, then I was there. I included a screenshot just in case that helps you.
Hopefully this solves your issue.
