I am exporting PDF files from Adobe InDesign CC 2017.1 on a MacBook Pro OS10.11.6. When I view them in Acrobat Pro DC version 2015.009 they all render properly. However, when they are opened on either an iPad or iPhone using Acrobat Reader version 18.02.28, the do not render properly at all. At first we believed it to be a font issue, but there are simple graphic boxes, either filled with color, or filled with white with a black key line that are not appearing at all and it's random. There is no set type of graphic, or font that doesn't render. One font could render fine on one page, but then on the next page isn't rendering at all. Same with the graphics.
Has anyone else had this challenge?
