Have the same issue here and can’t find a valid solution online. Have tried on my Mac and Windows, with both Endnote X8 and X9.
I have tried to replace the CrossRef connection according to an ealier thread but does not work. My scenario is that even though I provided title and DOI, “Find reference update” does not work at all, nothing can be found.
Any suggestions are sincerely appreciated. Thank you.
Best,
James
