Hello,
It's not a sync issue. Once you copy the screen, if the links have been copied correctly, it should be available for everyone. Your employees may have to refresh the page to get the new screen to appear.
If you have copied it from the screen itself (right-clicked on the screen and chose Customize) the links are copied automatically. If you copied the screen from the Screens page (Customize -> Screens), make sure you choose 'Replace links to an existing screen:' on step 3 in the copy wizard.
