Mobile usability with Storefront

Yes, I found it now.
So the problem now is that you can’t scroll search results box?

What plugin version number you are using on your site?

As I see you are using some plugins for assets aggregation. Please clear this plugins cache and test search form one more time.

Ok,

In this case please try manually add this code snippet

add_action( 'wp_footer', 'storefront_footer_action' );
function storefront_footer_action() { ?>
    <script>
        window.addEventListener('load', function() {
            function aws_results_layout( styles, options  ) {
                if ( typeof jQuery !== 'undefined' ) {
                    var $storefrontHandheld = options.form.closest('.storefront-handheld-footer-bar');
                    if ( $storefrontHandheld.length ) {
                        if ( ! $storefrontHandheld.find('.aws-search-result').length ) {
                            $storefrontHandheld.append( options.resultsBlock );
                        }
                        styles.top = 'auto';
                        styles.bottom = 130;
                    }
                }
                return styles;
            }
            if ( typeof AwsHooks === 'object' && typeof AwsHooks.add_filter === 'function' ) {
                AwsHooks.add_filter( 'aws_results_layout', aws_results_layout );
            }
        }, false);
    </script>
    <style>
        .storefront-handheld-footer-bar .aws-search-result ul li {
            float: none !important;
            display: block !important;
            text-align: left !important;
        }
        .storefront-handheld-footer-bar .aws-search-result ul li a {
            text-indent: 0 !important;
            text-decoration: none;
        }
    </style>
<?php }

You need to add it somewhere outside the plugins folder. For example, inside functions.php file of your theme or use some plugin for adding code snippets.
