Routing error between susch and zernez

Hi,

First of all: thank you! I really like the app and recommended it to other ev drivers.

I'm currently on a ski holiday, and noticed the app will not find a correct route between susch and zernez in Switzerland. The map just shows a road, but all planned routes lead you on a detour either eastbound or westbound for a detour of 110km, while there is a stretch of road just 6km long.

Other apps like Google maps route just fine trough here.

This is an example route:
