Tiktok is BROKEN Can't log in to my account

got a new phone and holy shit is tiktok frusterating. my account used my apple id. When I sign in it brings me to another account. wrong old account. When I sign in my apple Id again but use change phone number to change password, it brings me to ANOTHER account.

I had enough and searched my account up and copied and pasted the username, and. put my PASSWORD THAT I HAVE BEEN USING FOR YEARS.... said the password is wrong. So I go to change the password and I put the SAME PASSWORD as the new one. And says "You can't use your old password as your new" So it knows that its correct just doesnt want to work. I go change the password and then after verification code is wrong. I try again and use phone number instead to get sent the code. And it logs me into another old account for some reason.

This is with putting the same username of the account I want to log into. Tiktok is broken
