I hit the Summarize Video button while watching https://www.youtube.com/watch?v=jeCaw9EAvmk . Looking at the Chat GPT results of the Summarize button however, it had summarized the video I had previously watched, which was https://www.youtube.com/watch?v=faFruo5eugk . To its credit, the summary of https://www.youtube.com/watch?v=faFruo5eugk was pretty good. I had moved to the 2nd video by hitting a suggestion video thumbnail after watching the first video. I tried doing this twice with the same erroneous results, using the Youtube previous video button, then going forward with the browser forward button back to https://www.youtube.com/watch?v=jeCaw9EAvmk , and again hitting the summarize button. Again, the previously viewed video summary of https://www.youtube.com/watch?v=faFruo5eugk was generated, not the one playing on screen, which was https://www.youtube.com/watch?v=jeCaw9EAvmk
