KML → TCX: GPS route
TCX stores GPS route geometry, not KML map styling, overlays or polygons. GPS route lines are converted into GPS tracks; speed, heart rate and actual activity timestamps are not invented.
Upload KML with a GPS route line, not just map markers.
Check the order and coordinates of GPS points in the downloaded TCX file.
Check compatibility on your device; keep the original KML for map styling and other map features.
