TikTok Ban ??

How is she in Australia and not able to use tik tok? I get the shut down in America but she’s in another country and saying she can’t go on Tik Tok… I’m genuinely confused how that is.

If I went to Canada, could I use tik tok or no? I know this isn’t snark but I’m curious how this is. Or maybe Stinx is just dumb lol
