Klaviyo Featured Reviews Carousel Shortcode Not Displaying on WooCommerce After Adding Code Snippet to functions.php

Question

Hi everyone,I'm trying to display a Klaviyo featured reviews carousel on my WooCommerce website using the Klaviyo shortcode, but the carousel is not showing after adding the required code snippet to my functions.php file.The shortcode appears on the page as blank/no output, even though:Klaviyo Reviews is connected properly	Reviews are synced and visible in Klaviyo	The shortcode is added correctly on the page	No PHP errors appear on the frontend	Cache has been cleared	Reviews have been selected as featured on klaviyoI added the recommended snippet to functions.php, but the featured reviews carousel still does not render on the home page.Current setup:WordPress + WooCommerce	Theme: Astra	Using Gutenberg editor	Klaviyo Reviews enabledHas anyone experienced this before or knows if:the shortcode requires additional hooks/scripts,	there’s a conflict with WooCommerce templates,	or if the carousel only works with certain placement methods?Any help would be appreciated.

​@riquezamutibusinessgroupThanks for sharing all of that detail. From what I can tell, this doesn’t look like a WooCommerce or Astra-specific limitation so much as an installation-method issue.For WooCommerce, the featured reviews carousel is supported, but the setup is a little particular:If you’re using the raw widget HTML, that needs to be added to the HTML of the specific page where you want it to appear and not directly in functions.php.If you want to use a shortcode instead, the shortcode has to be registered first in PHP, and then you’d place [klaviyo-featured-reviews-carousel] on the page itself.Also worth checking: only reviews with text can be featured in the carousel.A few practical things I’d verify next:make sure you’re using one method cleanly (either page HTML or shortcode, not a mix of both)confirm the shortcode registration snippet is activeinspect the live page to see whether the carousel container is actually rendering in the DOMconfirm the Klaviyo Reviews JS is loading on the pagerule out a theme/CSS conflict, since that can affect widget renderingLet me know if that helps at all or if you were able to resolve yourself already.
