Loss of dot resolution proportional to length

Good morning, I've been using the Bike Map Cycle Travel app for a long time and for me it was one of the best ever for cycling, gravel and road trails, congratulations. I would like to draw attention to a problem that seems to me to have become annoying lately: that of long tracks. I noticed that the longer the route, the more the track loses point resolution, approximating the map and cutting the sharp curves. I noticed that it starts to lose resolution above 50-60 km in length, I hope for your attention to the problem, Thanks Franco
