Cant go Live ?

Hi, I have 1,800 followers. I can go live on Live Studio, but I don't have the 'Normal Live' option from the phone.
I used to have it for some reason, but then it disappeared.
I know there's something about age restrictions, but I can't find my age on TikTok (I don't remember what I entered when I first installed the app — I didn’t care at the time), even though I'm 34 years old.
Any suggestions?
