Hide album Set

How do you get the Feature Hide Album Set to function? Backlight 4

Edit an album or album set. Under the Privacy tab you’ll find the option to hide

I don’t see a privacy tab, A Features Tab with the Hide From Album Set option. Does not work. I must be missing something.

Must be the difference between BL4 and BL5

Are you still logged into Backlight in the same browser when you’re viewing these hidden albums? A feature of Backlight is that if you are logged in, you will be able to see any hidden albums.
Try looking in a different browser or log out of Backlight and try again.

Thanks a lot. That is the second time I’ve learned that.
