We used the app for our communication with our business partners in China.
We were pleased with the functionality of the app. But after 6 months or so, our account got blocked out of the blue with no further explanation.
Unblocking the account proved to be impossible after many frustrating attempts.

After contacting Wechat the only thing they give you is a standard reply referring to the same useless 'unblocking procedure' that won't get you any further in solving the problem.

WeChat clearly doesn't give a sh*t whether their users are able to use their app or not.
