If we want to use Strava Segment while following a course we have to create that course in Strava, be sure that the interested segments is one on our favorite segment, and then mark the Strava course as favorite one too.
In that way the course is exported and synced into Garmin Connect and the track presents at the beginning and at the end of our segments the markers to start and stop the live segment.
BUT! Why not all my favorite segments are exported?
Above all, why some personal public segments, marked as favorite, for example that are on flat terrain, are never exported?
How can I force a segment, even a personal one, to be traced into the course?
