@mariobeach not really aimed for ACF but it should work. You will have to localize the script as well. Add this to your functions.php or through code snippet plugin:
function enqueue_simple_address_autocomplete() {
// Enqueue the necessary scripts for Simple Address Autocomplete
wp_enqueue_script('simple_address_autocomplete_js_scripts', plugins_url('simple-address-autocomplete/public/js/simple-address-autocomplete-public.js'));
wp_localize_script('simple_address_autocomplete_js_scripts', 'simple_address_autocomplete_settings_vars', array(
'simple_address_autocomplete_google_maps_api' => get_option('simple_aa_options_google_maps_api_key'),
'simple_address_autocomplete_country_selected' => get_option('simple_aa_options_country', 'option'),
'simple_address_autocomplete_form_field_ids' => get_option('simple_aa_options_field_ids'),
'simple_address_autocomplete_bias_coordinates' => get_option('simple_aa_options_bias_coordinates'),
'simple_address_autocomplete_restriction_type' => get_option('simple_aa_options_restriction_type'),
));
}
add_action('admin_enqueue_scripts', 'enqueue_simple_address_autocomplete');
Also, when testing I noticed a bit of lag with ACF fields. Maybe couple of clicks but did work. Maybe the site I tested is slow or ACF when working with this plugin.
I hope this helps, let me know if there are any further issues.
Thanks
