Several times my 830 Edge has not followed the course unless I commence tracking right at the start. When I click "navigate to start" it does not navigate me to the start, it actually navigates me to the end (these are loop routes). Then the course ends without allowing me to follow the route. What is causing this error? Also, when I try to follow the route myself (without navigation or course) and then I select to start the course midway through the route, I cannot find any way to continue on the course route. The only option presented to me is to "navigate to start" as opposed to continuing along the route. At this point it does correctly navigate me back to the start, but then the ride completes without actually allowing me to go on the route.
What is going on here / what am I doing wrong?
Thank you
