I live in the New York City area. When using Maps on WP8.1 using my Lumia 820, I'm getting some very weird behavior with the traffic display. As I pinch to zoom in and out, the traffic shown keeps changing. At one zoom level, a road is showing red. Zoom out a bit, it shows green. A little more, it shows orange/yellow. Anyone else having similar issues?? It seems to be wide spread all over the city.
