Missed Priority Interview Deadline even though I submitted app before December 20??

So I submitted my application + writing supplement to Duke through the Common App on December 19 in order to meet the priority alumni interview deadline. However, after receiving an email to set up my portal today (and after doing so), the portal says that the application was received on December 21. Does this mean that I missed the priority alumni interview deadline, or am I misunderstanding something?

I emailed undergraduate admissions to check, but I was wondering if anyone here experienced the same thing. Just curious, please let me know - thank you!
