Cant access the editor mode with admin account


I just finished a project and I transferred the page over to the workspace of my Client. On this account, he is the admin so he somehow can’t access the editor mode. No matter from where you go into the editor mode, Webflow always asks you to log in. When you log in, it points to another way of accessing the editor … But it never works.

How can my Client access the editor mode using his own account?
