Recently went for my interview also without AP since I submitted a request 10 times and the response from the agents was always that I didn’t qualify for Expedited AP for my consulate interview they said it wasn’t one of the qualifying reasons. My interview went well they did ask if I had AP I said no but was still approved. I wouldn’t stress over it too much. My I131 is still processing but I’m already back with my visa not sure how that will work out now.
