I want to add new custom field in checkout/shipping and want to save them in the following tables in Magento 2.2.5:
I have referred this link https://codeblog.experius.nl/magento-2-add-extra-billing-or-shipping-field-to-the-checkout/
But it is showing the custom field in backend at customer section. But not able to see it in frontend
Any help would be appreciated.
