Hi @betsykleeverb !
The ICP license is actually a requirement from WeChat: any website communicating with the OA needs to be certified. And as a general rule, according to the cyber-security law of the PRC, the domain name’s registrar should be certified (i.e. Chinese) and the website should be hosted with a certified provider (i.e. Chinese).
I understand it can be quite a pain – this is not a requirement of this plugin in particular, though.
Re: website should be hosted with a certified provider (i.e. Chinese): this is because if the website gathers any data from CHinese nationals, it is required by law to be hosted on the Popular Republic of China’s territory.
