We use a PDF Viewer web object to load PDFs within the slide. It has been working fine in all our courses since 2014. However, in recent courses (built in Storyline 3), the PDF viewer is not showing all the features (especially zoom in/out buttons) in Chrome. It works well in IE and Firefox. This is happening in HTML5 versions of the courses only.
Can you please suggest what might be causing it and how can we fix it? Is there a new PDF viewer out there that works better with Chrome?
