We have talked a lot internally about replacing it with a better tool, and that is exactly what we are testing now.
The old route optimization was limited to a 50 waypoints, and was slow and could often end up crashing the browser. The new one is fast, and currently support up to 80 waypoints.
WE NEED YOUR FEEDBACK to help us consider if we should keep this feature or not. It comes with a lot of advantages, but also with a much higher price.
Please only submit this survey if you have actually tried the new route optimization.
Please also keep in mind that we've only changed the optimization process itself. The interface for selecting caches to optimize is the exact same as it was before.
