Can't scroll in my menu on mobile

Under the menu item Grupper I have a bunch of submenu items. On desktop the customer can see them all and the dropdown is scrollable. However, on mobile it’s not possible to scroll. I don’t know when the issue started because it hasn’t been like this since the beginning.

Can someone help me fix this? My website is seoulsound.se

Try this code:

nav.menu-drawer__navigation {
  max-height: calc(100svh - var(--minimum-touch-target));
  overflow-y: auto;
}

Can go to either “Header” section or “Theme settings” → “Custom CSS” or into your stylesheet asset…

Thank you!! ‎‎‎‎‎‎‎‎‎
