In the social media strategy course I've come across 3 quizzes so far where no matter which multiple choice option you select, all say the answer is incorrect. The correct one isn't displaying that it is in fact correct when you click it. For the first quiz in the section Expanding Your Reach On Social Media this is the concern as well as for the first two quizzes in the section titled Using Social Media To Build One-to-one relationships.
Thank you for reaching out to the academy community page! I'm happy to help out with this. Do you mind taking a screenshot of the questions you are referring to?
