I’m a foreigner living in Hangzhou and use Taobao on my iPhone. Some product pages show “We are temporarily unavailable in this area”; other times the page loads but checkout fails. I’ve updated the app, signed out and back in, checked my Hangzhou delivery address, and switched between mobile data and home Wi-Fi, but the result is inconsistent. My Chinese phone number was registered while I was travelling, so I’m unsure whether this is related to my account region, location settings, or the listing itself. What should I check next without risking access to my account? Has anyone dealt with this in China recently, in 2026, and found a reliable way to narrow down the cause?
