Dunno about Komoot, but you can’t download gpx files as advertised.
I recently paid to become a full member having perused the ‘benefits’ one of which is/was downloadable gpx files of classic routes. I won’t claim it was the deal clincher, there are of course more tangible benefits, but it’s there in black and white as one of the advantages of becoming a paid up subscriber.
Except it isn’t, because the links don’t work and you can’t download any gpx files. I reported this and was told (paraphrasing, it was a few weeks ago) that they know the links don’t work and are working on a better way of providing downloads. There was no timescale as to when this might happen, or suggestion it would be any time soon.
To my mind leaving this listed a membership benefit whilst knowing it isn’t, is borderline dishonest. I’m not suggesting there is deliberate deceit, but if you know it’s not going to be fixed soon because your developers are working flat out dealing with other issues, at least stop misleading potential subscribers by advertising it as a benefit in the interim.
