Unexplained deviation when exporting with gpx 1.2

[Jaap van Maanen]

I've been using gpx 1.2 for a while now, but recently I had some strange deviations in the route. Attached is an example where a strange turn is taken and you have to turn around to get back on the planned route. I have added images of one of the parts where things go wrong and I have shared the route as an example. With gpx 1.1 the route is correct.

The route was created with the Here map and is used on a Zumo XT with the latest maps 2024.10

This issue has been reported as #44839, but has been closed without a solution or explanation.

On the route of that day there were three issues. The following example had a similar issue at the roundabout.

If you want to use gpx 1.2 there need to be viapoints in the route, not only start en finish
