Add collaborator to form

Add Dr. Maria Chen as a collaborator on the course quiz so she can edit questions and view responses. Share with her university email maria.chen@stateu.edu and give edit rights this afternoon; do not change existing collaborators. Tell me when she has access.

Before I add Maria Chen as a collaborator, help me avoid version clashes. Recommend where to put an edit note so she sees recent changes, surface any questions with conditional branching that might confuse another editor, and list three quick instructions I should send Maria about how I name drafts and where I track scoring rubrics.

I just invited Maria Chen to collaborate on the quiz and she reports she only has view access. I'm afraid I accidentally gave the wrong permission level or used the wrong email, but I also don't want to remove other collaborators or break any response links. I don't know whether to re-invite, change permissions, or check sharing settings. What's most likely wrong and what exact steps should I take now to give her edit rights without disrupting responses?
