Have you enabled synchronization in Lightroom on your computer? Have you created a collection and marked it to be synchronized? Are you talking about that type of synchronization, or are you talking about something different?
No. I'm am trying to edit multiple images with the same presets.
Sorry. Do you have multiple images selected? And, do you have auto sync enabled? And, are you modifying the highlighted image? Also, what exact version of Lightroom are you using?
