Не работает вертикальный свайп на телефоне

Столкнулся с такой проблемой: Есть скрипт на свайп в стороны, все хорошо работает на ПК, но с мобильного устройства скролл перестает работать на данном блоке, т.к. все время пытается сделать свайп в сторону, и страницу невозможно больше скроллить Подскажите, пожалуйста, каким образом можно устранить данную проблему на Мобильных устройствах?

Скрипт:

class Slideshow {
