Apparently this App is discriminative against people from some countries in the world, especially the United States. It seems to be controlled by a certain political party. I submitted my application to become a host for a chatroom, but they never responded. Meanwhile, some other users from China got approved in no time. This is a politically oriented APP. Simply because I advocated animal rights, they denied my application. I never even mentioned anything political. Users beware. There are many language learning APPs out there, choose yours wisely.
