I'm a host and my guests are having the same issue.... lots of foreigners living in China and using Alipay, but Airbnb gives no explanation about why they receive the message "You cannot pay with this Alipay account" . You'd think they could at least say WHY they can't pay. Is it because they don't have a national ID linked to their account? If so, why does that only seem to affect Airbnb and absolutely nothing else? I use my Alipay to book train tickets, pay for hotels, use Taobao... so what's up with Airbnb?
