Hi there. I think what you might be missing is that usually for every lesson there are two tabs below the video that say "All Information" and "Tabs & Notation". Click the "Tabs and Notation" tab to bring it forward. The chords for the lesson should be shown there. I always click this tab BEFORE watching the video lesson, so that I can make sure I know the chords needed for the lesson, or learn them before proceeding with the video.

Hope that helps.
