Feedback: Video seek controls and reset completion status after content update

I generally like the new videos and appreciate the update. However, the current playback restrictions create unnecessary friction.

I understand the decision to lock skip-forward on the first playthrough so that learners cannot simply jump ahead. That makes sense from a content-completion perspective. What I find harder to justify is that skip-back / rewind is also disabled until the video has been watched all the way to the end once.

Even on a first viewing, people frequently need to re-listen to a short section immediately in order to fully understand it. Blocking that ability forces a purely linear experience that is more frustrating than helpful.

In addition, the “already watched” flags appear to have been reset when the new versions were uploaded. As a result, even users who have already completed the course and hold the certificate are treated as complete beginners and must re-watch every video in full at least once before any seek controls become available. This makes the common use case of returning to refresh specific topics unnecessarily inefficient.

Allowing rewind while still preventing skip-forward until a video has been completed once, and preserving existing completion status where possible when content is updated, would significantly improve the experience for both new and returning users.
