For the past few weeks, I've very frequently encountered an issue where the most recently edited file won’t sync. The only way to resolve this is to move the file out of Dropbox and then return it to its original location.
Strangely, when I move the file out of Dropbox, an older version of the same file appears. I then have to overwrite the old version with the most recent file that wasn’t syncing.
I'm using MacOS Sequoia 15.3.2, and my Dropbox desktop app is version v220.4.4126.
