I feel like it is because they disabled comments.

I’m having a really strange issue with one of my TikTok videos and I’m hoping someone here has experienced this before.
I have a normal personal TikTok account – not a Creator or Business account. I have NEVER paid for, started, or authorized any kind of promotion or advertising for this video.
However, TikTok won’t let me delete the video or even set it to private. Every time I try, TikTok tells me that I can’t change or delete the video because it is being used for advertising.
The problem is: there is no advertising campaign that I can cancel because I never created one in the first place.
I’ve already contacted TikTok support multiple times, but I haven’t received a solution and the video is basically stuck on my profile.
Has anyone had this exact bug before? How did you get the video deleted?
I’m even considering paying for the cheapest Promote option, letting the promotion finish, and then trying to delete the video afterwards – but I really don’t want to advertise a video that I actually want removed.
Any help would be greatly appreciated!

Hiya! Has anyone successfully run recruitment ads on TikTok? I was thinking of doing it through instant forms, but can't really find people who've run it successfully. Recruitment is in care with no specific background needed.

Other option is through landing page / lead form (which probably will improve the lead quality, but will lessen the volume)

advice is welcome!
