Zotero data not syncing
I've been happily using Zotero on my Mac, but yesterday was without my laptop and needed to use it online. To my shock, I discovered that data stopped syncing on January 25. I checked the documentation (https://www.zotero.org/support/kb/changes_not_syncing) and none of those issues applies. I also tried, as an experiment, adding a new record to the online account to see whether it showed up on my local machine, and it did--which means that I have not inadvertently created two accounts. I'm thinking of using the reset options but thought I should post here before proceeding. Many thanks in advance for any advice.
You were pasting images into notes in earlier versions, when it wasn't officially supported and could break syncing. Zotero 6 now properly supports images in notes, and in most cases it should automatically convert the images to the new, supported format the first time you view the note. Until you view the note, it will remain in the old format and syncing likely won't work.
