I added the jQuery found on the provided link (above) and set the offset to 0 but it offsets to the same place as before which is about ~140px too low:
jQuery(function () {
if ("undefined" != typeof FLBuilderLayoutConfig) {
FLBuilderLayoutConfig.anchorLinkAnimations.offset = 0;
}
});
I’ve checked in multiple browsers, Chrome, FF & Safari (clearing all cache) with the same result on my laptop. On mobile, it seems to work fine though.
