Playlist feature available to someone with only 400 followers? How?

Hi there,

My friend currently has 400 TikTok followers or so. They’re very consistent but have access to Playlists. They regularly use them. However, I notice when I go on my TikTok (I don’t have many followers) it says I’d need 10,000+ followers before accessing playlists.

I looked on their TikTok account and it says under the benefits tab on TikTok studio that Playlists is under the Benefits With Additional Criteria tab and not the 10,000+ followers tab. See image for reference*

The only thing done differently is that she has paid for TikTok advertising once. She is a lot more consistent than I so maybe that has a part to play.

Nevertheless, I can’t understand how she has access to this feature with only a few followers.

Any ideas?
