The checkout page functions of Rebato are exclusively available to Shopify Plus stores because Rebato utilizes the "checkout UI extension," a feature that Shopify makes available only to its Plus subscribers.

For stores on other Shopify plans, the ability to modify the checkout page is restricted, not due to limitations of the Rebato app itself, but because of Shopify's policy. This policy is in place to maintain a consistent and secure checkout process across the platform, with the enhanced customization options reserved for Shopify Plus members as part of the premium features offered by this subscription level.
