Hi @FOULONIne Thanks for reaching out and flagging this!
The submission confetti should still appear for on-time submissions in Assignment Enhancements when the Confetti for On-Time Submission feature option is enabled at the account level and has not been disabled by the individual user. We recommend checking in with your Canvas admin to confirm that this option is still turned on for your institution. If the confetti setting is enabled and students are still not seeing it, please submit a support ticket so our team can investigate further. We know this visual confirmation is important to students, and we appreciate you bringing this to our attention!
