What is different from the problems reported several months ago for me is that the route change popup will say that the route is changed, but the route doesn't actually change.
I do not believe that waze is currently working properly in regards to traffic avoidance. In fact for at least the last 24 hours, I see no evidence that waze is doing anything at all to route me around traffic. Waze seems to be simply routing me the way it would in the absence of any realtime information. This is despite an accident on my route this morning, many reports of traffic on the route, the freeway marked in dark red with low speeds listed and the popups saying that a better route had been found.
