If you’re extra attentive, you’ll notice that now when you switch pages in the Designer, you’ll see that the URL for your project has a unique parameter attached to the end of it (after where it says “pageId=”).
Copy this entire URL to link to this specific page within a project.
This parameter corresponds to the specific page within that project you’re viewing, so now you can copy and paste this URL to link colleagues and clients directly to that page of your project in the Designer.
