I've got a simple application working using mapbox-gl.js, and adding a marker layer with geoJSON. This works well if I use Mapbox's 'Streets' style, or if I duplicate the streets style as a custom style on my account.
However, I want to use a custom style based on the 'Light' style, and it appears that this doesn't include something that's required for displaying icons.
I've downloaded both styles as JSON, and swapped out the sprite
property, but that hasn't made a difference.
I've experimented with starting with the 'Streets' style and adjusting it to look the way I want, but that's a lot of changes to organise.
Is there something I can do, either in Mapbox Studio, or in the JS, to allow standard markers to be drawn?
