There used to be a visual indicator on the map, but I haven’t seen a single one this entire expac.
It seems to be bugged for specific people. My friend and I tested it and he could see the drops on the map and minimap but I couldn’t.
I was fortunate to get 1 last night. Flew around each zone with WM on and happened to be in the right place/right time. There was an emote that came across my screen, and a visual on my map. Looked like a yellow circle with wings and it was moving around. I landed on it and was the only one there. got 200 coins.
