Sync Settings not working

[dphershman]

I'm having an issue with synch settings all of a sudden.  Making changes in one file, I should be able to select another file and click the 'sync settings' to get the other files to have the same settings.  As of today, doing so does not export those settings to the other selected file(s).    The adjustment icons appear on the selected files, but when you look at the images in 'Develop' there have in fact been no synced changes.  I've tried updating my MacOS  (10.13) and my Lightroom (2015.12).  I've even reset my preferences, all to no use.  Thanks ahead of time for help.

FIXED: CLICK TEH AUTOSYNC BUTTON IN THE DEVELOP MODULE!

Sorry, but this is not "SOLVED".  This is an ongoing bug in 2022.  Shift Ctrl S on the PC should sync settings from one highlighted photo to another.  The bug is when you hit this keyboard shortcut, sometimes nothing happens, sometimes an export function runs, sometimes it works only in the Library Module, not the Develop Module.  The workaround is to reboot LrC.  This is still a bug in 12.0.1, Camera Raw 15.0.
