Why do my video posts not get any views or get onto the fyp?

Okay so i'm a writer and most of my tiktok posts are photo carousels but occasionally I want to post videos too but for some reason, TikTok just doesn't push it onto the fyp. Literally zero views!

Before that I used to post it and every single time without fail, it used to class it as ineligibile for the fyp even tho it was completely my own creation.

Now it doesn't do that but then is stuck at zero views so i've gone back to photo posts.

Is there any work around this? I don't want to be stuck on photo posts forever.
