Following the update of iTunes a few weeks ago, Apple has now released another update. This one brings bug fixes regarding playlist syncing. Before, there was a issue where playlist changes made on other devices may not appear in iTunes. Now, it has been fixed in version 12.4.3.
To get this update, users on a Mac can go to the Mac App Store updates page and look under Software Update. If you’re on Windows, you can use Apple’s update utility to download the latest version.
