I have 6 picture links on a mobile breakpoint of 768. 4 work, 2 do not, despite several things I have tried. When I copy the exact picture and the page in links to in a test site only with those items, it works. I cannot determine what the problem is in my multi-page layout, however. Any ideas? I am somewhat new to Muse. http://nationalfarmersconvene18.businesscatalyst.com/index.html
As the mouse hovers over the images it changes from "mouse pointer" to "hand", so there seems to be an overlapping element on mobile.
Even if this element is empty it disturbs the mouse behaviour, as you experienced.
Hope it helps?
