Further, there is resume button for another quiz when I come into the week 2. When I click the resume button, screen changed and then nothing visible. I cannot enter into or access the practice quiz I failed.
There are no answers for this problem in help center.
I tried contact us button or chatbot button in Help Center but no those buttons.
What can do? Who do I ask for?

1. Please clear your cache and cookies, log out, log back in, and try again.
2. Make sure this is not a payment issue. For example, in many courses, you can view the quiz questions, but you cannot submit your answers before paying or after your payment was expired.
3. If none of the above items solve the problem, then click "Contact Us" at the end of this Help Article:
