PDF rendering issue

My marginNote 3 app on Mac cannot display handwritten contents in a PDF file generated by Sony digital paper. My handwrItten notes can be rendered through MacOS 's original pdf reader but not by MarginNote3 itself even if I switched the PDF render setting. I have attached the PDF note so that you guys can check what’s wrong. Stokey_Lucas_notes.pdf (1.7 MB)

I have submitted this problem and your PDF to the developer.
