Hello,
When it comes to device type data available in CrUX, it seems that China is the greatest anomaly - desktop connections account for over 90% of all connections in China.
Why do you think that is? According to
this Wikipedia page, there are over 60 online restrictions created by the Chinese government. Is the government blocking the usage statistic reporting, which is more difficult to bypass on mobile devices? Or could it be that other browsers are much more popular in China for mobile users?
Best regards!
