nothing but wait.
i think different offices process applications in slightly different speed. that's why you see some people who applied later getting ahead of you. maybe you just got allocated to a slower team/office. when they give you AOR, it means they've checked your application to be complete. and if there's anything missing, they'll send you a request to re-upload something. so in some ways no news is good news. i'd just wait for another week or so.
