Search by identifier using DOI seems to have stopped working - any clues
All of a sudden I am unable to locate full citations with all the metadata using DOI. I've tested this using DOIs that Zotero was previously able to find and it not longer appears to work. PMID search on the other hand still works - but this usually requires extra steps and of course is not always available. Is anyone else having the same issue? Any ideas why. My version check says I have the latest.
