If the quiz widget doesn't appear on your live storefront, go through these checks:
Is the quiz published? — In My Quizzes, check that the quiz status is Published. Draft quizzes don't appear on the storefront.
Is the theme block added? — Go to Online Store → Themes → Customize and confirm the PerfectMatch: AI Shopping Quiz block is present on the correct page template.
Is the correct quiz selected? — Click the PerfectMatch: AI Shopping Quiz block in the Theme Editor and confirm the right quiz is selected in the block settings.
Saved the Theme Editor? — Make sure you clicked Save in the Theme Editor after adding the block.
Try a hard refresh — Clear your browser cache or open your store in an incognito window.
