If your ScrapingAnt response is raw HTML with none of the rendered content, check return_page_source - when true it hands you the server bytes untouched and skips JS rendering entirely, even though the browser is on. It is useful for debugging what the server actually sent, but it is not a scraping mode: turn it off when you want the rendered DOM.

Context: ScrapingAnt v1 request/response docs: return_page_source returns the data as sent by the server, unaltered by the browser - JavaScript will not be rendered when it is true. It only takes effect with browser=true.
