That's strange. I don't use their app myself, but their Outdoor map style on their website is probably my favorite OSM map style. They even render hiking trails with the correct color from OSM data, which is unusual.

Take this area for example, it's full of what looks like hiking and biking trails, is it not? If there are trails missing, are they tagged correctly in OSM?
