If you are experiencing this Canvas bug, there are two ways to troubleshoot: making a substantial change to the name of your quiz or copying the quiz to another course and back to the current course.
Substantial Name Change
- Select Quizzes from the course navigation.
- Locate the quiz, select the three-dot menu, and select Edit.
- In the name field at the top of the quiz setup page, make a substantial change to the quiz name.
- Select Save.
- Locate the quiz, select the three-dot menu, and select Duplicate.
- Click on the duplicate and select Build.
- Verify the quiz is the most current copy.
Copying Out to Another Course & Back
- Select Quizzes from the course navigation.
- Locate the quiz, select the three-dot menu, and select Copy To.
- From the dropdown, select a course into which you will copy this quiz. (A sandbox course is recommended.)
- Select Copy.
- Navigate to the second course (the course you selected in step 3).
- Repeat steps 1-4, this time copying the quiz back into the original course.
- Navigate to the first course and verify the copy is the most current version.
Note that you may combine the two methods above (copy the quiz to a second course, make a substantial name change, and copy it back) to ensure Canvas sees they copy as a new assignment ID.
