I created a router that protects pages from members who don't have some credential. The code works as expected on live website.
The code does not work on preview because it not possible to simulate those credential in preview. That cumbersome but I understandable.
The router kicks in while in the editor, redirecting me when I try to edit a page protected!
I know this feature is not the most used but if think this is a pretty big issue for the editor
