TikTok views went down after promo video

Hey guys, I've been facing an issue lately and I'm not sure if it's fixable. A few months ago I promoted one TikTok hoping to reach a bigger audience, but since then my views have been horrible. I used to get 4000 views on a good video and around 500 on a bad one, but now it's a struggle to reach 200. Anyone else facing the same issue after promoting something? I know my lack of views is the platform trying to make me spend money, but I don't want to have my views depending on that. Is there any solution or did I basically lose my account? I'm a small artist and losing that account would be really bad since I have a few followers there already
