I'm unable to download pdf documents, I can't even view it because it says of invalid format. I have downloaded a pdf reader so it's definitely not that? This concerns me as I need to view my course material.
Why are you not able to download pdf's? Any pdf, or only those from your course/school? You say you have a pdf reader, can you download the attached pdf document and see if you can open it. It's just a picture of a cat.
I cannot view the kitty file. I have a new Samsung Galaxy S7 and have been having issues opening pdf's I used to open on my old S5. Dowloaded adobe reader and no help. Please help me figure out what happened.
