MacOS: 15.7.7
Dropbox: 260.4.2926
It seems this issue has been happening for a while, when searching files/folders through spotlight or Finder, no results are shown. Making the files/folders available offline do not make them show up. I've tried the following without success:
Spotlight Privacy > Click the plus and select "Macintosh HD" drive into the privacy list. Wait about 30 seconds, then select the drive and click the minus (-) button to remove it. It may take around 30 minutes or so but macOS should re-index the files
Reinstalling Dropbox, force quitting/relaunching Finder.
If anyone has a solution, please let me know.
