Trouble Using Adobe on Android

@Admired_magnetism4141 The error message: This form requires Adobe Acrobat Reader DC for Mac or Windows opens bcause it's a specific type of PDF form that contains advanced features, often called XFA (XML Form Architecture) forms. Even if you have the latest Adobe Acrobat Reader installed it might not open in a web browser's built-in PDF viewer or Apple's Preview app on Mac. Instead, of using your phone, you need to use the computer, save the PDF file to your computer's desktop or a specific folder, rather than viewing it in the browser window.  Open within the Adobe Acrobat Reader DC application itself, and navigate to the PDF you saved.
