PHP error: Deprecated functions

When Constant Contact + WooCommerce plugin is activated, I get these PHP errors:

[27-Apr-2023 19:30:07 UTC] The WC_Customer::get_address_2 function is deprecated since version 3.0. Replace with WC_Customer::get_billing_address_2.
[27-Apr-2023 19:30:07 UTC] The WC_Customer::get_city function is deprecated since version 3.0. Replace with WC_Customer::get_billing_city.
[27-Apr-2023 19:30:07 UTC] The WC_Customer::get_country function is deprecated since version 3.0. Replace with WC_Customer::get_billing_country.
[27-Apr-2023 19:30:07 UTC] The WC_Customer::get_postcode function is deprecated since version 3.0. Replace with WC_Customer::get_billing_postcode.
[27-Apr-2023 19:30:07 UTC] The WC_Customer::get_state function is deprecated since version 3.0. Replace with WC_Customer::get_billing_state.

These errors appear even if I deactivate all other plugins except WordFence, and switch to Twenty Twenty Two theme.

The errors do NOT appear if all plugins are activated EXCEPT Constant Contact + WooCommerce, and my child theme of Flatsome is active.

Investigating your plugin, I found this file: CheckoutHandler.php

I commented out several lines in this function:

	/**
	 * Return array of address fields we want.
	 *
	 * @author Michael Beckwith <[email protected]>
	 * @since  2.1.0
	 */
	protected function get_the_address_fields() {
		return [
//			'address_1',
//			'address_2',
//			'city',
//			'country',
//			'postcode',
//			'state',
			'shipping_address_1',
			'shipping_address_2',
			'shipping_city',
			'shipping_country',
			'shipping_postcode',
			'shipping_state',
			'billing_address_1',
			'billing_address_2',
			'billing_city',
			'billing_country',
			'billing_postcode',
			'billing_state',
			'billing_phone',
			'billing_email',
		];
	}

Now the errors no longer appear.

Please fix this!
