Several possible reasons: -Cookie consent not granted – some tests require marketing cookies to activate. -Unsupported platform – we may not yet support the tool in use. -Server-side test – server-side experiments often don't expose client-side data. -No active experiments – the site may not be running any tests at the moment.
