I’m new to PaperPile, and so far I like it a lot.
I have imported a sizeable number of references (more to come), and many of the pdfs have annotations (of the type that I can make or edit with apps like Preview). These annotations appear if I view the paper with the Chrome default viewer, but not with the PaperPile annotating viewer and not on the iOS app.
How do I import the existing annotations into the PaperPile system (in bulk)? And conversely, how can I turn PaperPile annotations into pdf annotations that third party apps could read?
