- Open a quiz administration page.
- Add a user(s) or group and select what permissions you want to grant:
- Can view and edit
- Can view
- Apply changes.
User who you added into page permissions will be able to work with a quiz.
Don't remove izi - LMS for Confluence user from quiz page permissions. This is the app user that is needed for quizzes to work.
