Wheel pointer doesn’t appear on tablet/mobile

Hello! We’re unable to see the wheel pointer on mobile and tablets. Here are the methods we’ve tried:

changing color settings

disabling all plugins but Lucky Wheel

modifing these css rules using media queries:

h.wplwl-location:before {
    content: "\f100";
}

.wplwl_pointer:before {
    font-size: 170px !important;
}

.wplwl_pointer:before {
    font-size: 500px;
}
.wplwl_pointer:before {
    color: #ed1c24;
}
.wplwl_pointer:before {
    text-shadow: -4px 2px 0 rgba(0, 0, 0, 0.2);
    font-size: 55px;
}
.wplwl-location:before {
    content: "\f100";
}
[class^="wplwl-"]:before, [class*=" wplwl-"]:before, [class^="wplwl-"]:after, [class*=" wplwl-"]:after {
    font-family: "wp-lucky-wheel";
    font-size: 20px;
    font-style: normal;
    margin: 0;
    padding: 0;
}

can you help? We’d like to leave our site info private but would be happy to provide credentials/url in an email ??

many thanks in advance
