I'm trying out Pure Maps as a replacement for Here WeGo and it's really nice to see a native Sailfish app being on par or (in some parts) even better than a commercial Android app.

Would it be possible to use Here as a backend for routing and search, though?

The two back ends I've tried so far (Stadia Maps and OSM Scout) both seem to ignore the "no toll roads" and "no highways" settings completely which is slowly getting expensive
