I’m jealous! Can’t seem to get to work in the US. Where are you from? It is a US problem?
I live in Sweden. Hmm, I seem to recall the Trump administration banning WeChat, there was a lot of fuss about it back then, cause all of the Chinese, no matter where they live, use it. It's a useful app if you have a lot of Chinese friends, and for those living in China basically a necessity, since they use it for almost everything. But it's heavily regulated/controlled by the Chinese government, gathers a lot of information about the user, and Wechat are legally required to share all info with the government if asked, which I think was one fo the reasons it was banned in the US. I use it with certain caution, though for me as a foreigner it's a bit safer to use.
