mapkitJS HTTP-401 Unauthorized only for Mainland China

Hello there,

Mainland china user(s) have trouble accessing MapKitJS, keeps returning HTTP 401 unauthorized for https://cdn.apple-mapkit.com/ma/bootstrap?apiVersion=2&mkjsVersion=5.77.35.
The same valid JWT perfectly works for users rest of the world.

May i know is there any special handling needed for accessing mapkitJS on web from mainland china compared to rest of the world.

Advises are highly appreciated.
