Theme support depends on the placement and current theme behavior. The table separates three checks on Horizon 4.2.0 from the named Dawn and Focal integrations, which have older private checks. It does not promise compatibility with every theme.

The product page, cart page and cart drawer are separate placements. Results for one surface do not prove another.

Check the saved state

In Shopify’s theme editor, turn on the Pairwise theme embed and press Shopify’s Save. Return to Pairwise and use Check again where shown. Then verify the shopper placement and explicitly publish only reviewed offers. Opening the editor does not save the setting or publish an offer.

If your theme or placement behaves differently, pause the affected offer and contact Pairwise support with the theme name, version, and surface. Do not change another app’s cart behavior while troubleshooting Pairwise.

Read go live, cart placements, and product-page add-ons for their separate checks.
