However I can try to describe what I mean. When on mobile when you open the navigation bar you can't scroll down far enough to see all the navigation links, or the navigation doesn't scroll itself allowing you to see all the nav links.
Perhaps adding some kind of overflow scroll to the mobile navigation could fix this minor bug. Though I haven't updated to the newest version yet, I just finished working on the theme before the new oxwall update so I am waiting a bit for my members. Don't wanna have to do it all again as I have to do sometimes on theme or platform updates.
