I am making some simple updates to my site and selected the option to "upgrade" to Fluid. OMG what a freaking mess my page has become. Also, why cannot move a form from one section to another. You can't drag it and you can't copy/paste it! This is probably the worst editor I have ever used and this is coming from someone who has lived through the Wordpress Gutenberg nightmare. Who at Squarespace thinks this is a good product. I am considering moving my suite of sites off to another platform when my customers ask for updates because this is, no joke, the worst experience I've had editing a website.
