Changes made in settings are not reflected in checkout

Problem: While configuring the InPost app and simultaneously checking the checkout page, the changes made in the app settings may not be immediately visible.

Cause: This occurs because Shopify caches the proposed delivery methods for a given cart for 5 to 15 minutes, causing a delay in updating.

Solution: Return to the shipping address form and make a small change, such as adding a character to the last name. This will prompt the system to retrieve the updated shipping methods.
