The "Use example video" walk-through does not permit simply clicking through the demo. On the "This is the section where you are going to write your annotations." div, when you click the bottom next-arrow to proceed, it insists "Please, write a title and/or a body".

Users wishing to quickly "scroll" through the demo, are thus prevented from using that style of perusal. Some will punt. Perhaps this is an intentional tradeoff, sacrificing some, to increase engagement of others? It might be interesting to A/B test that. Perhaps the "user provides video url" and "use example video" cases might be handled differently? Perhaps a "Continue with worked example? y/n" instead of the error, to still nudge towards engagement, but with a lower barrier to "I just want to see your thing - why are you stopping me?"?
