The empty account walkthrough is the step I'd move to the top, because it feeds the landing page too. If you record that run with clean sample data, you get the screenshot of a meaningful result and a short clip of the first useful outcome from the same session. One more check for the screenshot item: open it at the size it will actually show on a phone. Labels that look fine on a laptop are often unreadable in a listing thumbnail. And I'd match the "known limitations" note to what the screenshot shows, so the visual never promises more than the copy.
