Can't Log Back Into My TikTok Account

I have been unable to access my TikTok account on my iPhone 13 since Thursday morning due to a repeated “device not recognized” type of error. Even though I have previously logged into this same account on this same device and I have not changed my login details recently, TikTok keeps refusing my login attempts. Each time I try to log back in, the system does not accept my access and simply refuses the login. When I try to reset my password, I also receive the same “device unrecognized” message and cannot complete the password reset process. I have tried to resolve this through TikTok support, but I am repeatedly met with the same questions over and over again without any real solution or progress. I request that my access to my TikTok account be restored and that the security check on my device be reviewed so that I can log in normally from my iPhone 13 without further unnecessary restrictions.
