Yes it still works. You have to follow the steps exactly though. So not through the regular friends bar but through the Z2 menu.

Alternatively, you can travel to the outpost of the player you want to unfriend and tap their avatar/IGN in the top right corner and click the red minus button.

Hope this helps.
