I am starting to use an editor for images and sharing a Smat Preview LR catalog with them over Dropbox. They just emailed me back asking me to check their edits marked in yellow before they proceed. I opened the SP LR catalog right from the shared Dropbox folder and cannot see their edits. They do not know the answer to this. Do I need to resync on my end? They edited directly from the Dropbox folder as well.
How are they making the edits and making these edits available to you? Can you please describe the process in a lot more detail?
