The issue is not with the site as it appears on mobile. It’s with the site on desktop devices.
The top level menu items (that include a dropdown) require two clicks to function correctly.
The headings links within the dropdown also require two clicks to function correctly.
I’m fine with the way these links work on mobile, but they should only require a single click on desktop devices.
My client and I are concerned that this incorrect functionality in the menu is going to impact conversions.
