- Application : App inventor
 - Embeded Map : OpenRouteMap
 - Component : Map, Marker, LineString, Navigation
 - Problem : Suddenly LineString is not pointed
 - Map is OK, Marker is OK,
 - Token Key is OK
 - Not Key quota issue.
 - Navigation component returns points, distance and duration but nothing returns at all. So lineString is not effected.
 
Thanks
