HELP-Zotergo doesn't recognise pdf
I would like to safe this Pdf file ( https://www.ciel.org/wp-content/uploads/2019/02/Plastic-and-Health-The-Hidden-Costs-of-a-Plastic-Planet-February-2019.pdf) and this pdf file ( https://sci-hub.tw/10.2903/j.efsa.2016.4501) but zotero doesn't recognise it. What is the problem ?

BTW, the EFSA Journal is Open Access, so you might have better luck downloading that paper from this address:
https://efsa.onlinelibrary.wiley.com/doi/epdf/10.2903/j.efsa.2016.4501
Zotero recognized that PDF for me.
