About 1.5 weeks ago my user notes stopped syncing from my laptop (2011 MacBook Pro, OS X Yosemite). My iOS devices continue to sync the files properly. When I make a change to a user note on my laptop and select sync, I receive the message, "nothing to sync." I've unlinked and re-linked Accordance to my Dropbox account to no avail. Please help me to diagnose and fix this issue.
