Hello,

Navigate to WooCommerce > Settings > Shipping > Shipping options: http://prntscr.com/l5enph

Default to customer shipping address
Default to customer billing address

In this two cases, user will have the option to add shipping/billing addresses if they are different.

I this case, “Force shipping to the customer billing address” only billing address will be available for shipment.

Our theme does not influence these settings.

Best Regards
