@RuthWinnett -
It sounds like you are using New Quizzes (but I don't think it would matter if this were Classic Quizzes). Do you have general feedback for the MC and TF questions? If so, do you see that in your view of the quiz in student view?
What question types are not showing the general feedback?
Also what are the exact settings you are using? Include a screenshot of the settings if possible.
For new quizzes I can see the general comments as a student - in the settings here I did not have anything checked.
For Classic Quizzes I have the let students see their answers checked and they can see the general comments for the question types I checked.
