Slick slider - double tap bug on iOS

Question

I have a problem with slick slider. It makes me double-click the buttons to make them work properly. For example "zobacz całą ofertę" button or "go up" button. It works badly only on iOs. On Android, Windows, iMac works perfectly. Can someone tell me what it's wrong? On subpages without slick slider everything is ok.

(function ($) {
  $('.carousel').slick({
    dots: false,
    infinite: true,
    speed: 500,
    autoplaySpeed: 5000,
    fade: true,
    cssEase: 'linear',
    autoplay: true,
    appendArrows: $('#arrows'),
    nextArrow: '<span class="slick-next slick-arrow"></span>',
    prevArrow: '<span class="slick-prev slick-arrow"></span>',
  });
})(jQuery);
