Order fields are empty

Hello,

I’m now trying to use your Calculate Prices Based on Distance for WooCommerce Pro plugin (latest version) on WooCommerce 9.9.5 to collect pickup and delivery addresses (street, city, postal code, country) plus delivery date/time at checkout—and automatically send them via the Shipday API when the order moves to processing.

Problem:
Your checkout fields render and calculate distance/pricing correctly in the cart, but none of the pickup/delivery inputs (including date/time) are passed on to WooCommerce’s order meta or into Shipday’s payload.

Could you please advise which hook or filter your plugin exposes—either PHP or JavaScript—so that I can reliably read the user’s pickup/delivery address and date/time at checkout and save them to order meta? Any specific examples of how to integrate with block-checkout or the REST payload would be greatly appreciated.

Thank you for your help!
