"Mapbox deprecated support for Mapbox Studio Classic styles on June 1st, 2020"
(https://docs.mapbox.com/help/troubleshooting/migrate-legacy-static-tiles-api/#faqs)

Following this change, the MapBoxTileSource is not working properly anymore, at least for Satellite maps (which is my use case). Setting MAPBOX_MAPID to:

• "mapbox.mapbox-streets-v8" gives names only, unusable.
• "mapbox.satellite" gives satellite image without names and roads.

The new MapBox Static Tiles API is documented here: https://docs.mapbox.com/api/maps/static-tiles/
The new url pattern is now: "/styles/v1/{username}/{style_id}/tiles/{tilesize}/{z}/{x}/{y}{@2x}"

For instance, this url works fine for a satellite view with names:
"https://api.mapbox.com/styles/v1/mapbox/satellite-streets-v11/tiles/2/2/1?access_token=THE_ACCESS_TOKEN"

=> MapBoxTileSource needs some adaptations.
