have you try using the browser extension like Live Stream Downloader?
-The content MUST be from TikTok, do not post slips from other platforms.
-You MUST include profile names / link to the profile, or make every attempt to include it.
-Include timestamps if you post a long video or a full live video.
-Make sure ALL girls posted are 18+
If they haven't changed the back end you could also just do it in browser with network inspection tools to grab the direct media file. Been a while since I have tried.
