Slide up not working iOS

Hi WP-Tiles team,

You have a great plugin and your efforts are very appreciated.

I came across something odd, where the slide-up feature works perfectly fine on desktops & laptops (Windows, Linux, Mac) and Android devices, but for some reason, it does not work on iOS devices.

I tried both with an iPad and iPhone running the latest iOS, and the slide-up functionality does not work when you “touch” any of the titles.

This is the site where I have the tiles:

Have you seen something like this before?

My team already deactivated all plugins to test if there was a conflict but found nothing.

Any light you can shed will be very appreciated
