    I have first tested the Advanced Form Designer on some of my own forms, and the Designer is applying the changes instantly.

    I have cloned your form into my account for further testing, and I can replicate the issue with your form, so it looks like the issue appears only on your form. I can see that LESS CSS is unable to compile the CSS codes on your form, and is providing this error in the browser console:

    "less: RuntimeError: error evaluating function `lighten`: a.toHSL is not a function in https://www.jotform.com/themes/css/style.less on line 3036, column 14:
    3035         & when not (@collapseBgColor = null) {
    3036             .gradient(lighten(@collapseBgColor, 10%), @collapseBgColor);
    3037         }"

    I have forwarded this as a bug report to our developers, so they can examine the problem and fix what is causing it.

    We will let you know through this support thread when there are any updates regarding the issue. Thank you
