I understand this issue has been in discussion as far back as 2014, however, the recommended fix did not work for me (or many others) according to past discussions.
I have a course with a final assessment at the end. The assessment is set up to draw questions from a question bank, and I am using the built-in "Review Quiz" and "Retry Quiz" buttons. Regardless of the number of correct answers the learner has, when the review quiz button is clicked at the completion of the course, ALL questions show as 'answered incorrectly'.
I have tried the recommended setting in the slide properties (setting "Automatically decide" and "Reset to initial state" but that did not work for me.
I'm running the latest version of Storyline 360, and I've updated to make sure I'm up to date. Any help would be appreciated.
