Q9 : Why Google Map does not show all of my waypoints on the track?

You probably have enabled “Optimize track waypoints” function. It can revise the track and remove redundant waypoints automatically. If you want to see the whole original waypoints, please just DO NOT select the “Optimize track waypoints” function.

You can right click the mouse on the Track which you want to use “Optimize track waypoints” function, and click “Attributes” (please refer to the picture below).
