Videos are locked from getting new segments when all the segments have been submitted to prevent spam. I don't know your exact situation, but you are probably mad by either
1. a decision to leave in a certain sponsor disclosure that is required knowledge for the video due to it being required to know the bias of the speaker in the video (example: a fully sponsored "review" about a product, you can't just skip the sponsor disclosure) 2. segments being submitted under the self promotion category that you do not agree with (just enable that category in settings to skip those too) 3. It is a new video, someone submitted stuff before you and you need to refresh
