Note: As of 1.21.60.25, this issue appears to be resolved (at least for the create world screen; I am unable to access the new edit world screen for some reason). A screenshot of the fixed menu is attached as resolved.jpg

The old create/edit world screens had the option for "Invite Only" for PlayStation Network, however this option is currently missing from the new version of those screens.

The absence of this feature makes it so that you cannot currently set your world to "Invited users" for PSN friends through the new create/edit world screens. This means your world will always be open to any of your PSN friends unless you entirely disable multiplayer, which isn't ideal.

This isn't currently a priority as the old edit world screen is still accessible, allowing you to at least go back and edit your worlds to be invite only, however with the eventually replacement of JSON UI it will be crucial that there is at least feature parity between the old and new screens.
