Every time I try add a citation in Google Docs, I receive a message saying "Zotero is updating your document. Please wait…" I cannot write/edit in the doc when this message is displayed, and the red progress bar comes up behind the Google Docs window. However, nothing happens after this and there is no way to add the citation.

I have tried disabling the extension, redownloading the app, restarting computer/browser etc etc and nothing seems to work.
