Kanban not working on my mobile device

I’m using a Kanban board, and everything works perfectly in preview mode. I can drag and drop items between columns on mobile, tablet, and desktop views. However, when I test it on my actual mobile device (iPhone XS Max, iOS 18) using Chrome or Safari, the drag-and-drop doesn’t work, I can’t slide items between columns. Has anyone else experienced the same issue? Could it be related to my iOS version? I can’t upgrade this device beyond iOS 18, so I’m wondering if that might be the cause.
