Slider in smartphone

Hello everybody. I have created the web otroconsumoesposible.com with the theme Clean Journal. Some time ago, I do not know when and why, the slider does not work in smartphone. I can see the slider without problems in Mac, but not in the mobile. It takes some minutes to charge, and then I only can see one of the three pages of the slider. Could you help me, please?
