ungraded final after 11 days?

[Tswede]

You have 23 days. You will be fine. Contact Cody regarding the issue – they're required to submit your work back within 3 business days (Mon-Fri).

Actually Cody explained to me when I inquired it's 72 hours, not 72 business hours.  Either way though 11 days is way excessive and you should involve Cody.  Cody encouraged me to reach out to him and the professor in a joint email after 72 hours including weekends.
