How do I open a URL to a PDF in Edge?

Question

How do I open https://dps.mo.gov/dir/programs/ohs/grantstraining/documents/nsgp-nss-inv-just-form.pdf in Microsoft Edge? When I navigate to it, I get this response:

Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document. You can upgrade to the latest version of Adobe Reader for Windows®, Mac, or Linux® by visiting http://www.adobe.com/go/reader_download.

I get the same response on Chrome. I tried setting Adobe Reader as my default viewer and Edge as my default viewer. I tried on 3 computers and get the same result. The browser version is:

Hi @Phil D'Angelo

It's an XML Forms Architecture (XFA) PDF file which is a legacy format of forms that isn't supported in Microsoft Edge by default.

To open it in Edge, you can enable support for XFA in PDF in Edge flags like below:

Besides, please make sure you're not using the new PDF reader powered by Adobe Acrobat in Edge. Please make sure this policy NewPDFReaderEnabled is not configured. Then you can open the PDF in Edge.
