This issue has be recreated:

• Locally

• With only LifterLMS and a default theme

It makes sense to say they can't start a new attempt, but I think they should be able to resume and complete the current attempt. We should hide the "You are not able to take this quiz" in this scenario.

Also test "Next Question" and "Complete Quiz" if resuming the last question.
