While riding a course I downloaded from Komoot, and not navigating to the beginning of the course, the gps indicates several times I've reached the end of the course, even while I've only ridden a couple of km's. I then have to restart the course to continue the ride. It also directs me back in the direction I came from several times. Does anyone have the same problem and how can I fix this? Is it because the course intersects a couple of times?
