when I label a PDF, there will be several situations where the PDF page is always on and out, but the PDF content does not appear, and the second is: display error, modification cannot be saved to the document (how big a PDF will appear cannot be labeled, ( Add a PDF greater than a certain MB can not be labeled why not in the help or prompt inside the instructions, my PDF size is 60MB I can not label, a twenty MB can) because of this problem I gave up impression notes as a knowledge management tool, because i usually have a lot of PDF files need to be read and labeled,
