Nav Menu Remove box shadow for mobile menu

The submenu box-shadow isn’t responsive and we’re unable to find the correct CSS to disable the box-shadow in the mobile menu. Just to calify, we want it to show on desktop but not on tablet or mobile.

We had a similar issue with the border around the drop menu icon that was solved via this users post: https://wordpress.org/support/topic/how-to-remove-the-border-around-the-submenu-indicator/

We currently have this in our CSS to fix the previous issue, looking to add the one to fix the shadow now:
@media (max-width: 1024px)
{.ekit_menu_responsive_tablet .elementskit-submenu-indicator
{border: none;}
}
