It is high appreciated about your support.
We found the string of waypoint will be cut if too long.
When we download GPX into ST, the name of waypoint group are similar (ex. gpxwaypoint1) and will be ingored to only one. It is a little inconvenient.
Sorry for the late reply, I just noticed your message.
About the name being cut, that's a limitation of the watch. In the communication protocol I can only send 6 letters, all the rest has to be cut.
You can load waypoints with the same name to SportTracks, but not into the watch, because it identifies waypoints by its name (for example to delete some waypoints you need to specify their names), so if there's already a waypoint with the same name, it will be overwriten.
I hope I clarified your questions.
