I am an instructor. I have posted all grades for a quiz, but my students still cannot see them. They are not hidden; they are not muted. I have gone to course settings to make certain the Hide totals in student grades summary is unchecked. My 'instructor view' page is showing me that every student should be able to see their grade. Some students can see their grade, but not the quiz or my comments. Other students can see nothing except, "Quiz results are protected for this quiz and are not visible to students."
