OK, we'll just wait for now. I just wish there was a wait to get clarity as to what is going on. If the NVC had responded and said something definitive like you have to wait X more months. Or you have to wait for the final action date to be current. Or as you said, it takes a while for the website to work or catch up - it would at least help.
The other concern is that the welcome letter said that if nothing is done without 12 months, it would be treated as abandoned. I can't imagine we'll have to wait 12 months to pay the fees, but that deadline is also in the back of my mind.
