TikTok allows users to repost content but doesn't provide a straightforward way to undo a repost.
To undo a repost on TikTok, open the app, find the video you reposted, select the arrow icon, choose 'Remove repost' from the menu, and confirm the removal.
There is no limit to the number of times you can undo a repost on TikTok.
Undoing a repost can help clear up your followers' feeds and is useful if you accidentally shared something or changed your mind about supporting a video.
