Buttons not working on mobile/table

Hi all,

Having an issue with my site where the menu button and case study links don’t work when on mobile/tablet viewpoint. I’ve tried modifying the z-values and still no luck.

Any ideas as to why this keeps happening?

Have you checked if there might be overlapping elements or if there’s a CSS property like pointer-events affecting them? Also, ensuring that there’s no JavaScript error or conflicting scripts could be worth looking into.
