Hey just 1hr back I got enrolled to this 3 months course but I didn't find any update in the dashboard ...can anyone help me with this

This might help you: I have enrolled to this course without logging/signing it in with a mail ID, and couldn't see the dashboard, as there is no account logged in. But later I have signed up with the enrolled mail (Mail given while enrolling), and dashboard could be seen when I logged in with that mail.
