I just got the pop-up that EndNote needed to update, so I ran the update. However, afterwards, the cite while you write option in Word 2016 did not work anymore.
When I want to add a citation, it does not automatically add itself to my reference list anymore and it shows up, in text, like this:
The NPS is a tool to measure customer loyalty, the higher the score, the more loyal the customer Reichheld, 2003 #18}.
I have the same problem. Turning on Instant Formatting does not do anything. I still have all the citations as, for exmaple, (Dortmans, 2017 #100), and nothing appearing in the references. I am using the latest version of Endnote9.
Endnote is usually set to use curly brackets as delimters for temporary citations {Dortmans, 2017 #100}. these can be set in Endnote’s preferences settings (edit> preferences>Temporary citations delimiters) or in an individual word document on the Endnote toolbar/ribbon in bibliography dialogue menu. (see image)
DO NOT try to use normal parentheses, or every parenthetical item will try to be interpreted as a temporary citation.
