I haven't tried that one Jack, but there are a few that I have struggled with and I am not sure if it is because of photogrammetry. Some will have the obvious spinning volanta sign, but others I have got from just being in the area for a short period of time (seconds not minutes - like the new Airbus delivery location). Others I am starting to wonder if the photogrammetry is getting in the way of triggering the find. I will give that one a go soon, but did you land there and sit for a while?
