The video is approved, but the wrong caption went live. Where is the fix?

Make approval apply to the post package rather than the media file alone. Store the approved caption alongside the exact asset and account. If the caption changes after approval, the workflow should make the new version visible to the person responsible.

Investigate the handoff that allowed the mismatch before adding another reminder. A clear version boundary, preview and final confirmation can prevent the same class of error across future batches. The remedy for an already published mistake should follow the platform and service workflow actually available.
