Problem with a retake quiz not showing up

I have a module where I see the retake quiz button when I preview as a learner. But a user sent me a screenshot without that option visible; unsure why that is the case, but the learner failed the quiz and can’t proceed. I am unsure how to give them access to the quiz again so they can pass and complete the course. Any thoughts and suggestions are welcome.

Is it possible to redo a simulation once completed?

Is there a way to enable a learner to redo a simulation? Currently, if a learner has successfully completed the simulation, and revisits it at a later date it loads to the last “Well Done” slide.
