huuduy216 On mobile? Not sure how that would look but u can try:
.item-discussion-views:before {
font-family: 'Font Awesome 5 Free';
font-size: inherit;
content: "\f06e";
margin-right: 5px;
}
This piece of css is disabled for screens where the width is under 768px (= mobile). If u add it into ur custom css the icon should be always visible i think
