Can't use stickers?

Went to comment on a tik tok with a sticker, no option for stickers. Closed the app. Opened again. Nothing. Closed it. Updated the app. Opened. Still nothing.

It won't let me do it on any tik tok. I also literally used a sticker just yesterday.

It happened like almost a week ago aswell, but it fixed after I updated the app. Didn't fix this time.
