Hi, this mightn’t be a support issue so much as a user knowledge issue 
When I use a Navigation Collapsed element in my header, I have some items in the top level of the menu that lead directly to pages (e.g. Home, Contact, etc) and others that have sub-items as well (e.g. About, What We Do). My question relates to items that have sub-items as well as leading to a page (e.g. About)
When using a full navigation element (i.e. on a desktop), I can either click on the top item itself and go to, say, the About page, or I can click on the Sub-Indicator and reveal the sub-items.
When using the Navigation Collapsed element on either the screen size simulator or, indeed, on a mobile device, if I touch the top level link, it reveals the sub-items. Touch it again and the sub-items disappear. It looks like I cannot have the top level items pointing to a page - I am unable to choose the page that it points to.
I hope that makes sense!
Cheers
Neil
