Several times I have noticed the app direct me to leave motorways, go straight over the roundabout, and merge back onto the same motorway, same direction.

So I tried a route along the same stretch of motorway using openstreetmap.org website to check if it was a problem in the map data but could not reproduce the problem.

I have screenshots of this issue but for some reason I can no longer attach images on github.

Maybe related to #353?

Ah yes, this looks like the same problem.

I've been seeing this issue on organic maps where I wouldn't see it when using osmand. I can post the specific highway if needed, but it seems like a routing algorithm issue rather than a data one to me (but that's just a hunch)

Please share exact coordinates for us to debug and test. Also, please, double-check that the route wasn't broken in the OSM data at the time of our maps data generation.

@shompoe please share start and end coordinates, a link to the OSRM router on OSM.org would be even better.

Oh wait, I remember what road and was able to reproduce it in the app. Starting from Margate and going to Hemel Hempstead (United Kingdom). On M2 at junction 4 is where the error occurs.

I'm sorry, I don't know how to do this.

That's an intersection where the issue occurs if you route from a couple miles west of there to a couple miles east of there (and vice versa) so that the route uses the highway
