How to Fix It

Try the Duet button on a different video — if it works on others but not one specific video, the creator has disabled Duets for that video.

Creators can turn off Duets per video in their privacy settings when posting.
Check your account age in Profile > Settings > Account — accounts under 16 have Duets restricted.

TikTok applies age-based restrictions automatically based on your birth date.
Make sure your account is not set to private: Profile > Settings > Privacy > Private Account.

Private accounts have limited access to collaborative features like Duets.
Update TikTok to the latest version from the App Store or Google Play.

An outdated app can cause features to appear missing or broken.
Check if your account has any active restrictions: Profile > Settings > Report a Problem to contact TikTok support.

TikTok may apply feature restrictions to accounts that have received policy warnings.
