I created a support case in Komoot with the GPX and a photo that shows the offset. I should not (this is not my job) but it’s also I can do with my track. I’ll keep this thread updated with their info (if there’s any). I also sent comments in the Suunto App.
I made some manual fixes but I’m not sure that an edit of the passing points will make any effect. I also fixed the end at that mountain in Komoot but this is not good at all . I should not edit anything downloaded (in this case I know the track, but that will not happen in a track of a place I have never been).
So I’ll test this edited track. I understand I have (at least) fixed the end at the top of the mountain (and the out of the route and the bad climb guidance notifications will not be triggered in that point), but the rest is really a mistery.
Perhaps Route Planner is the solution. If you can make the imported GPX tracks have turn-by-turn, that’d be really fantastic.
