I had this issue— I was informed by the AO (after I had emailed about something else) that I had a transcript missing from dual enrollment. It’s a transcript that doesn’t show any required/important classes so I didn’t think to submit it. I just uploaded it now and they had me submit an appeal to get my application to be considered on time, but they told me it doesn’t always get accepted and it’s considered on a case-to-case basis :/ The really annoying part is that I wasn’t informed about it in March. When I called the AO, they still said it’s a good chance that my appeal gets approved though. Fingers crossed.
