I'm confused, you say 'I guess they didn't have our documents' but then say they scanned them? You have to take the documents on the checklist (mainly originals of the ones you've uploaded to NVC) to the interview, but it does sound like you've done that.
The online status will say refused or AP whilst final checks are done, and then change to 'issued', usually within just a day or two. As long as it's a straightforward case and not a high risk consulate, hopefully it will be super quick.
Good luck.
