Drop Down issue

Hi,

I have a strange issue on mobile and tablet.
I have a dropdown menu which works perfectly well (parent item as well as children) on desktop (and emulators) but on phone and tablet, clicking on the parent item has no effect.
Do you have an idea why?

Thanks in advance for your help

Sandra
