TikTok ban effecting users in Australia

I live in Australia, the phone I use was bought in Australia and has never been used in the US, 4 years ago I used to live in the US and that is where I opened my tiktok account and even though I no longer am located there it still says I can't use TikTok because of the ban in America, what the hell is happening and why is it effecting users that are located in countries that have no bans in place this is inaccurate and unfair. I don't use a vpn or anything like that.
