Hi, how can I add a smooth slide-up and slide-down animation for answers in a collapsible content section?

The animation works on desktop, even when I resize the store to mobile dimensions, but on an actual mobile device, there’s no animation.

How can I make sure the animation works on real mobile devices?

Thanks for the help!

Hi, i just notice your faq section is working slide up slider down is it solved.

It works on a computer, but when you check it on an actual mobile device, it doesn’t.

If you open the store on a computer and switch to a mobile resolution, it still works, but on a real mobile device, it doesn’t. How can I apply it for mobiles too?
