I am trying to call an ACF value from a woocommerce product so I can display in to an invoice but having issues on grabbing the specific information for that. I’ve added a screenshot of the ‘Internal ID’ which is the ACF field and value. I need to add that to the following:

We would like to allow customers to provide additional data for their exisiting Woocommerce orders as the service expiry date approaches (preferred collection time etc.).

We have an ACF field added to Woocommerce orders storing date on which reminder should be sent to customers (text field with date in d/m/Y, field ID ‘reminder’). Would like to change order status on that date to identify orders where reminders have been sent. I have found and modified a piece of code that I hope we can use, but struggle with how to access and pull in the date from the custom ACF field to trigger order status change.
