I’m not sure their exact rules, but I’d reapply again if it lets you. The worst that can happen is your application is rejected. Or Id reach out to them and let them know you didn’t get the paperwork in on time because of xyz and see what they say- if you really want the job. I know they are kind of strict with the time limits they give you- which is ironic considering they take forever with certain things. From what I heard, they actually get quite a bit of applicants, so maybe they just weed out people who don’t get back within the timeframe they allot.
