I am having trouble saving items from Springer Link. When I hover over the Zotero Connector, it says "Save to Zotero (Springer Link)". When I click on it, the pop-up says "Saving to" and the name of the collection I've chosen. The box eventually disappears without having saved the item to Zotero. Saving works fine on other sites.

This has happened with all the Springer Link articles I've tried to save in the last couple of days. Here is one such article:
https://link-springer-com.uml.idm.oclc.org/article/10.1007/s11104-018-3787-2

Thanks,
Joanne
