+> At the moment, tnktok.com is currently being transferred to another registrar and therefore cannot be used until then. Any updates will be posted in [#2](https://github.com/okdargy/fxTikTok/issues/2)

+>  In the meantime, I recommend using [tiktxk.com](https://tiktxk.com/) (s/o/x), another amazing TikTok embed fixer created by the [Britmoji](https://github.com/Britmoji) team.
