commenting with pictures and stickers feature is gone for me

so i have had this feature for more than a year but lately it's no where to be seen! i waited foe it to come back for a while but nothing i tried to remove the app and download it again today it came back for few moments then after i finished setting up the account it vanished again i wanna know if anyone has this problem and how can i fix it 🥲 + my birth date on tiktok is 2006 which is my real birthday so i don't think it's an age issue since I'm 19...
