Document View Function Across Devices

Question

a!documentViewerField 
 
 This function specifically, I have gotten it to work, by displaying a PDF file through creation of constants and inserting documents etc. However, my issue with this is that, though it works well on Desktop/Laptop, the additional features such as scrolling, printing, saving the document, editing, annotation, fit to window, rotate, search, functions are not available on Mobile/Tablet devices. 
 Minimally, I want to allow my users to scroll up and down, why am I unable to do so?

Mobile devices use native PDF viewers with limited features. Use conditional logic, show download link on mobile, viewer on desktop

This component is not designed to work the same way in mobiles as it does in desktops! As per documentation : On Appian Mobile applications, the document viewer component appears as a document download link. The value provided in altText is used for the link label. 
 So what you are expecting is not supported in Mobile devices. Rather users can only download the document.
