Permalink in new application builder

Hi,

how can I get a permalink with no log in required? it seems that this feature has changed with the new application builder.
When you follow the "publish" link you get to a new window where you have a check box for a no-login option however this seems to do nothing... Going back to the old builder does not help either as this option seems to be disappeared?...

Thanks
Luis
