Mapbox maps not updated from OpenStreetMap recently?
I've noticed that around here (east London, UK), the background maps using tiles from Mapbox have not been updated to incorporate changes from the underlying OpenStreetMap.org data. This is likely to become more of a problem due to the amount of ongoing redevelopment of the area around Queen Elizabeth Olympic Park, as the Strava maps become increasingly outdated and inaccurate.
e.g. London Marathon Community track, enclosed by OSM way https://www.openstreetmap.org/way/500928305 (last edit affecting geometry in changeset https://www.openstreetmap.org/changeset/55267707 ) over 7 months ago is still not visible in the background maps used by Strava. There Strava heatmap data shows the presence of a running track fairly unequivocally https://www.strava.com/heatmap#18.52/-0.01574/51.53681/hot/run
