In the app our guys can access pdfs with drawings and other documents in the collaborate section, however when they open them via the app the pdf appears blurry. There is a download button (pointing down arrow) but, on an iPhone, when you click this it opens the share menu rather than actually downloading. They would then need to send it to themselves to open a readable copy. Same thing happens on our android tablet. They open perfectly fine when opened on a computer or via the web browser on an iPhone so there is no issue with our documents. The download button needs to be an actual download button or the pdfs need to be clear when accessed in the app.
