Ionic 5 ion-slides breakpoints property not working

Ionic Framework
1

After upgrading to Ionic 5 cannot resize the slider after passing the breakpoints property into the options. Were there any breaking changes in terms of the ion-slides component options?

slideOptsFour = {

    autoplay: {

      disableOnInteraction: false,

    },

    loop: true,

    slidesPerView: 3,

    breakpoints: {

      // not working

      500: {

        slidesPerView: 2,

      },

    },

  };

Just noticed that it is now >= 500px and not <= 500px like it used to be, which is weird. So basically I need to rewrite options the other way around.
