Hi the performance of the map is very importance to our mobile app. Right now, the map take 8 to 10 seconds to finish loading in our react-native mobile app. We checked the performance of the map via the browser tool and found out that most of the time is handle the basemap/basemap tile loading? We want to package the basemap/basemap tile into the mobile apps to improve the performance, how can we do it? If yes, Can we only package the NYC portion of the basemap/basemap tile into the package?
