I was in similar mode not exactly same.
My AP came thru, my wife's did not. Both applied at the same time. Although, her receipt number came up online but with pending status.
I followed up multiple times, but they asked me to wait for 4 weeks.
Later I called up the Senator's office representing my locality provided them with Receipt Number. Within a week I had the AP for my wife.
The online status is still showing as pending.
Now the timing of the 4 week wait and I calling the Senator's office was around the same time. So I do not know the magic behind but something worked.
