How do I manage confetti animations in Canvas as an instructor?
If you run the link validator in your course and no invalid links are found, Canvas may display confetti. The link validator celebrations feature option must be enabled by your institution's Canvas admin. However, if you prefer to disable confetti in your account, you can manage this feature setting in your user settings.
Note: Assignments set up with external tools as the submission type do not display confetti animation upon a student's submission.
Open User Settings
In Global Navigation, click the Account link , then click the Settings link .
Manage Celebration Animations
In the Feature Settings section, click the Disable Celebration Animations state icon  and select the Enabled or Disabled option .
Note: If the Disable Celebration Animations feature setting does not display, it is not been enabled by your institution.
