Vanishing insert citation menu

In google docs. I click insert citation. The menu opens. But before I can get there it turns into a white box. And then closes itself.

Welcome to the forum @Konrad_Kording and I’m sorry for the trouble you are experiencing. Are you working on a collaborative document? We’ve received some reports of the Insert citation dialog not working properly when multiple users attempt to type in the document when another user has the Insert citation dialog open, and the team are still investigating this issue.

Can you try reloading the Chrome extension: go to chrome://extensions, switch the Paperpile extension off by toggling the switch, then on again, then reload your tabs, and let us know how that goes? You can also try restarting the browser: in Chrome, you can type chrome://restart in the address bar and the browser will restart and reopen all your tabs of the current profile. Another option is to use our Google Docs sidebar add-on: it will allow you to insert citations and format your reference list.
