Same problem here, really annoying. Have to resort to reading & annotating on my phone which is less than ideal, especially since now I can't even use Preview to annote PDFs without this error appearing "The original document can't be changed, so a duplicate with your changes has been created" (see attached). I used to be able to simply open a PDF in Preview and annotate the original, without having to save a copy and then re-import to evernote.
