1. The Android app continues to use Google Maps which is Great Firewall blocked, meaning I had to use a VPN to load uncached tiles.
2. Uber in turn IP blocks EC2, preventing me from using my main VPN while in app.
3. Entities on the map are shifted by the GCJ-02 offset (https://en.wikipedia.org/wiki/Restrictions_on_geographic_dat...), meaning entities on the map are shifted by 0.5 miles (look at those cars driving on parkland: https://www.dropbox.com/s/hhkrjyka5uq0pfb/PeopleUber.png?dl=...)
4. User support was absolutely non-existent. After I responded to an automatic email from the local community manager inviting me to ask any questions, I only received an automated emails telling me I won't be helped.
5. Help pages in the app on Uber China tell me to see the Chinese translation, with no actual link to said translation.
While the foreigner use-case in China is niche, the sheer amount of obvious (and easily resolvable) problems I ran into suggests that Uber has organizational problems ensuring both drivers and customers have good experiences in foreign countries.
One blog from Jan 2014 highlights how bad the execution was at launch: https://www.larrysalibra.com/5-problems-with-uber-in-china-a... - the most absurd being that Uber (at that time) only accepted US-branded credit cards which few Chinese nationals hold.
