Egress IP and device position differ
A VPN affects traffic routed through its connection; it does not imply a GPS change. Apps with location permission may use device position. An IP lookup and a map may show different areas, so a map alone does not establish whether a VPN works.
Check IP and location permissions separately
Compare egress IP before and after connecting in the same browser, then review the target app location permission. Android device location and per-app permissions are separate controls. Keep needed map permissions instead of disabling everything. Note whether the page uses IP or granted location.
Different region displays need context
Sites may also use account details or previously selected regions. Read their explanation before diagnosing the network; no route guarantees every app shows one country. Use the routes available in Yunbao and report page results without revealing a precise home address.
