I have the Lumia 925 running Cyan version 8.10.12393.890. My region settings are set as Country / Region: China, and Regional Format: English (Canada). I was under the impression that Cortana was available in China (as Xiao Na, or even as the default). However, I do not see it in the list of applications under Settings, where I can turn it on/off. Can somebody please help me get this going?
