tiktok on pc has a business suite, but not tiktok on mobile? how to get back a personal account on PC

i was on pc and opened messages on tiktok, and got a prompt that i can "level up my account". the results of levelling up the account seemed harmless (it didn't say i was upgrading to a business account) so i levelled up. i got access to a business suite immediately but when i check my account on mobile im still a personal account. how do i fix this? im not a business and i heard business accounts have to worry about music and copyrighted material more than usual. the only way i can even access this business suite is on PC via messages.
