Remove a Playlist Share

If you have shared a playlist with other teachers in your district, and you no longer want to share it you can remove the share from those teachers without removing the playlist itself.

Select My Library on the top menu bar.
Select the 3-dot option for the shared playlist, and then select Share.
Select Remove next to the teacher(s) you want to remove the share from.
When you are done, select the X to close the Share Playlist box. Teachers who you have removed the share from will still see the playlist in Shared With Me, but the playlist will be disabled. They can then remove the unshared playlist.
