Updated Information Issue

So I sent an update to all of my RD colleges regarding an award I won, and I got responses from every one (excluding the ones which required me to upload it to their portal) except for one college. I got responses in 1-2 for all of them, and it’s been 10 days now. The college in question was one I had sent a LOCI to, and I heard back in 5 days from the regional admissions officer when I sent that in. They told me to keep them updated on anything important, so I replied to them in an email to let them know about the award. Well, it’s now been 10 days, what should I do?

Do nothing. Admissions officers are swamped right now so you should not expect a reply to every email.
