This has nothing to do with the feedback master or the accessibility (objects). When you program a quiz, you can add a "review button" at the end (with a pre-programmed trigger), so the student clicks on the "review button" and is shown the individual quiz slides marked as "correct" or "incorrect" In those slides (being reviewed) the (seeing) student is also shown a checkmark next to the correct answer. Screen readers do not recognize the check mark. So, a student using a screen reader may mark something wrong, and in the review process, they will know it was marked as incorrect, but they will not be able to hear the correct answer. That is the issue. The green checkmark is what isn't accessible. This violates WCAG 1.1.1 Non-text content, and it appears (according to one of my colleagues) that this has been a known issue since 2021 (disappointing).
