I am running Bespoke UX 9.3.4 and when I try to load the wizard or preview it the page does not load. I have to refresh the page sometimes many times to make the page load. When it loads it functions fine. In another Org I am running Bespoke UX 8.15.7 and I have the exact same page and I have no issues previewing or using the page. To me it feels like a bug.
