We have built a web platform that lets kids read books, record videos, and video call to other people via real time chat. Recently we have entered into the China market, and hosted our platform on Aliyun Cloud in China. But because of China's Firewall, that censors internet and blocks potentially unfavorable incoming data from foreign countries, it is slow and have all sorts of tech issues - e.g. network connection terminated for no obvious reason, can't do video call etc. We need you to come up with a methodical plan of approach to do software testing, debugging, identifying where issues need to be fixed, browser testing, testing environments, test scripts, error logs and error handling, exception handling etc.
