Hi, I'm trying to plan a trip and for the first time I'm having trouble on a specific section of a route.
I was able to isolate the problematic route, from Sankt Moritz (CH) to Zernez (CH).
Even with a SOC at 100% with a Zoe50 2020 it won't allow me to travel straight between these two points but sends me North through Alvaneu Dorf, Davos and then Southbound again to Zernez.
Forcing tens of guidepoints will give me a very complex tour of 613km and a gap on the straight route (which is 35km long according to OSM).
Would you look into the issue please?
Best,
Paco
