My bibliography keeps disappearing
Im almost done writing my thesis and haven't had any trouble with Zotero until recently: whenever I add a new citation, this citation appears underlined (with a dashed line) and my whole bibliography disappears. I then usually click "refresh" on the Zotero tab on word, and a few times the bibliography reappeared, but often it would direct me to the Zotero app and nothing would happen. This has happened multiple times and is very frustrating, so any insight will be very helpful. TIA
Which word processor are you using?
Beyond that, you're very likely just not waiting long enough for the bibliography to be regenerated. It would've asked you to turn on this mode specifically in situations where updating the bibliography was slow.
