OCR / Text Recognition in PDF Files

OCR / Text Recognition in PDF Files

It appears to me that OCR does not work consistently with all PDF files.  I've begun migrating from Evernote, and Evernote would always find text in any type of PDF file or image file.  Nimbus Note can't seem to recognize text in certain types of PDF files.  From what I have seen, if it is a PDF with text embedded in an image it will not be recognized.  As of right now, as much as I like many of the other features that Nimbus offer, this is a deal breaker for me.  Can you please confirm if this is a known issue and when it might be resolved?
