What happened to my short-form content all of a sudden?

I post both vertical short-form and regular long-form as I was invited by Tiktok a while back to start uploading long-form and got automatic monetisation (though as you need at least 1000 views or something per video I don't actually earn anything). I've been uploading since late 2023. My long-form gets around 300 views each, while all short-form is pretty much only in double digits. However, recently, something changed, and now my short-form videos literally get 0-1 views each. Long-form still gets the same 200-300, but the short-form ones just don't get pushed at all now. Any ideas what happened?
