I created a pdf of an annual report created in inDesign CS6. Looks great on all of my devices. When my client opens the files on her iphone and ipad she can't see any of the body copy. The initial caps work fine. The initial caps are OpenThe body copy is a truetype font. Fonts are embedded in the pdf.
My client does not have this problem viewing any other pdf on her devices. Is there a preference or setting I am missing that is creating this problem?
