Exported GeoJSON data missing

[buehda]

I exported the cycle lanes of switzerland as GeoJSON, but when I import it on Mapbox Studio, many of the vectors aren't showing up as they should. Some of them disappear when zooming in, but I have no idea why and how I can avoid that.
The preview in Overpass looks fine, but in Mapbox it doesn't. Could anybody help me with this? Thanks!

zoomed out is ok:

zoomed in there are missing a lot of vectors (this is only a sample, there is more missing if I zoom further):

The request was like this:

/* Velowege */
[out:json];
(
  // get cycle route relations
  relation[route=bicycle]({{bbox}});
);
out body;
>;
out skel qt;

Try to open the exported GeoJSON in https://geojson.io and see if this works. If yes, better check with Mapbox why the GeoJSON isn't working in their map.

Thank you! I found out that I have to convert the data, so that Mapbox doesn't compress it. Now it works.
