Hello,
Yesterday I was tinkering with my website, and created new unlisted blank page. I was prompted with new tutorial tour for "Fluid Engine" it is really really sweet, but so far only that one blank page has this new option, if I create a new blank page or a section it resides to a "Default-layout engine", and there is no way to obtain new designing feature. Any clues why I am able to have this special treatment to a single page but not others? 😄
Here is the only resource I found online about the update - https://support.squarespace.com/hc/en-us/articles/6421525446541-Fluid-Engine-Squarespace-s-new-content-editing-experience#toc-identifying-fluid-engine
Thanks!
