Post-purchase offer limitations
Updated today
Shopify has some limitations on its post-purchase checkout extension, so the post-purchase page won't appear in certain cases, no matter which app provides the 1-click upsells feature.
Post-purchase upsell offers won't display in the following situations:
Checkout method: the order isn't placed through Online checkout.
Multicurrency orders: the order is placed in a different currency than your store currency, or has duties applied.
Local delivery: the order uses local delivery.
Accelerated payments: the order is paid with Shop Pay, Apple Pay, or Google Pay.
Local payment methods and installment-based gateways: the order is paid with one of these (like Klarna, Afterpay, etc).
Gift cards and store credit: the order is paid with a gift card, store credit, or any method other than a credit card.
Subscription products: the order contains a subscription product.
