I don't think change the region or language in the setting will fix this problem. I even connect my iPhone to a VPN server in U.S, it still doesn't work. I finally closed the location service in case Apple identifies me by locating me. All in vain. It is very easy for Apple to identify where are you from, probably by the network you connect. I'm not proud of being born in China, the worst evil dictatorial censorship nation in the world, nor do I appreciate Apple being so smart to identify my location.
