Unable To Authorize My Apple ID Login For Tiktok

I have deleted my tiktok app off my phone after trying to fix a further problem with the app, once I redownloaded it and I tried to login with my apple ID it said “unable to authorize, please try again”. I kept doing it and doing it and it worked for like a week then the problems started happening again so I deleted the app and reinstalled it. Now it has been two-three weeks of on and off deleting and reinstalling the app and nothing has worked. I have tried changing my password or logging in with different platforms and everything is saying unable to authorize, I have even tried making a different account in general and that doesn’t even work. I don’t know if it’s my phone or if it’s tiktok itself. (I have an iphone 12 mini, I got it in November 2022.).
