* If you upload GPX traces to #OpenStreetMap but you set their visibility to private, then of course won't render in the GPX layer. But if you later set them to a more public level, they won't either. See https://github.com/openstreetmap/operations/issues/1202
@mdione I never got my head around the OSM GPX privacy levels. Too many options that never really made sense to me. I think I end up choosing a random one each time.
@SteveBennett I uploaded a couple as private because I wanted to map what I traced. Later I figured out it didn't make sense, so now they're all public.
