In the past couple of years, modern web browser have add the feature were you can open PDF’s directly in a windows without open Adobe Acrobat or another PDF reader/ writer.
This is all fine and good until those PDFs have complicated forms. Then you get an error such as, “Please wait … If this message is not eventually replace by the proper contents of the document, your PDF view may not be able to display this type of document.”
To solve this issue, force your web browser to open PDFs externally.
In Chrome go to chrome://settings/content/pdfDocuments and slide this setting on.
In Edge go to edge://settings/content/pdfDocuments?search=pdf and slide on.
In FireFox goto about:preferences#general , scroll down to Applications and change Portable Document Format to “Use Windows default application”.
