    Thanks for flagging. Our check shows downloading the PDF is fine. That message is usually a browser viewer issue; please use "Download" to open in a PDF reader or try a different browser/private tab. If it still fails, please reply with your browser + version and OS so we can investigate further. Thanks again for letting us know!
