Hi Ed, I filed an enhancement request as suggested: FB24931853 — system-managed offline road maps for third-party MapKit apps. I’m developing a cycling app, iBike. Offline road maps are important in rural and mountainous areas where GNSS may still work but cellular coverage may not. A track/polyline alone cannot show the surrounding road network. We are also interested in support for mainland China. Posting the FB number here as requested. Thank you.
