You can establish what country will appear as a default in your Address field. Simply go to your Form Editor within the form builder and click on the Address field to open its Edit Field panel.
You’ll find a dropdown list labeled Default country, where you can select the country that you want to have preselected when users access your form.
The first option in the list is Autodetect. With this option enabled, the form can detect the country where your form users are located based on their IP addresses. Their location will then be preselected in the Country subfield.
