When looking to sync multiple players with a playlist there are two ways to do it:
1) Sync: Select the playlist you want to sync and turn on the Sync button and at the Master field add the name of the master player. This playlist must be published to all players that need to be synced.
NOTE: Please confirm that the players to sync, are under the same location.
This option requires you to manually publish all the players even if the selected playlist was previously published.
2) Tags: First you need to create a Tag going to Content > Tags section and create the tag considering the following elements:zy_syncPrimary:PrimaryPlayerName
Add the Tag to the players that want to be sync in the tag sections in the players details (By Filter > Player details > Content tab) you will find the Tags button.
If the players previously had publish the playlist to sync, then only add the tag to the players and wait a few minutes for the sync to start. If you have not publish to all the players it requires to manually publish the playlist. Players must be under the same network and location.
NOTE: Make sure all players that you have assign the tag will have the same playlist.
You can have both options active at the same time but keep in mind that the tags option will rule over the sync properties.
