Route calculation has stopped, have double checked that all waypoints are on roads but still not working, plus although I'm a gold member I can't raise a support ticket as it isn't recognising my gold membership. grateful for some help please - thanks
The error ZERO_RESULTS is often Google Maps letting you know you placed a waypoint on a currently closed road.
A lot of roads are currently closed due to seasonal closures.
However if you were to use the HERE map (GOLD) you are able to still make the route even on the closed road.
I hope this helps you!
Thanks Anthony, thats it - really appreciate your help
