I get mixed results when asking Gemini to summarize videos. Sometimes it works perfectly, other times it just says I have an invalid link. My hypothesis was that YouTube creators had some sort of option to opt out of AI-related tooling, but maybe there's more to the story. Edit: here's a random example, I picked a recent penguinz0 video (https://m.youtube.com/watch?v=UbXYzFEh-bw&pp=ygUJcGVuZ3Vpbnow https://m.youtube.com/watch?v=UbXYzFEh-bw&pp=ygUJcGVuZ3Vpbno...) and it just gives me a message saying "I'm just a LLM I can't help you".
