How to fix object on the map on unity mapbox

I am trying to build a navigation application. i can find to route between user and a point, but my problem is the point is not fixed on the map. I mean that when i scrool the map, the chosen point are moving.

How to i fix this point on the map?

 

You'll have to update the route's points whenever you scroll the map manually.
I assume you convert your input to a map scroll value somewhere, you will have to add these values to the points' coordinates.
