Im also confused about this because my status is "Under Review (A)" so in theory my application was marked "complete" so I assumed that the "complete" status indicated that all the supplemental application requirements were met. It felt weird to find out that they didn't accept my LOR
after I was marked as complete. Felt like this is something I should have been told beforehand (TUCOM CA let me know about this issue before I paid the secondary fee) but oh well
🙁 time to email every single science professor I've ever had to see if someone will do a last minute LOR for me
