Hello, I am starting to work on my paperless system with Evernote premium. It has been going well except one problem.
A PDF file can be opened successfully with Evernote on my PC, but when I try to open the same file on my Android phone or my iPad, it can't be opened, mentioning "file is not a valid PDF". This problem only happens to one particular PDF file out of the manys in my database so far.
I wonder if anyone encountered such a problem before? What caused this and how it can be avoided? What I am worrying now is the other PDF files in my database... and also the reliability of using Evernote to store my database containing many PDFs
