The Online Order field previously labeled Default Service Region has been renamed to Fallback Service Region (If None Matched) and now includes the option to be cleared.
Additional information about this setup:
If a customer's address does not match a service region defined in the Service Region Map within Service Region Setup, the system will default to the service region specified here. If no fallback service region should be used, and no options should be available when an address falls outside a region map, leave this field blank.
