Login redirect apparently works perfectly but when a user creates a new site (with Pro Sites) and gets the message "You're all set up and ready to go. View your site or go to the admin area.", if he clicks on "admin area", he goes to /wp-admin and not the url that was set inside Login redirect.
I saw a " / " is added after "/wp-admin" but I don't know if it's important.
I can't understand the reason why.
