Not able to access the course videos and content even after completion of filling the pre-requisites
0

I have enrolled for the course on y’day .But even after completion of the introduction and filling the pre-requisites it is showing the message as incomplete and Iam not able to continue to start accessing the contents.Pls help

Please ensure that after you watch a video, you press the button “Mark as completed and continue”.

It isn`t working.It is saying ‘Prerequisite(s) have not yet been completed!’.
I have watched each video now twice.
So please fix this issue.
As i am unable to move to next week.
