I'm using Sitefinity 5.2 and the responsive design tools. For some of the main navigation areas we're currently using the Navigation widget and marking them as "horizontal".
When these load into responsive size, they stack vertically (we may have helped them do that with some extra CSS), but they are not clickable through to the next page. This is true on iOS and Android devices.
On iOS, tapping on a navigation link will visually change the link to an "active" state, but it doesn't leave the page. On Android, tapping a link doesn't change anything at all. And furthermore, when trying to swipe the page up (scrolling), if your finger first taps on a navigation link, it won't scroll the page, so you have to consciously avoid the navigation.
Is anyone familiar with what's causing this? Mobile devices don't have Firebug, so we're scratching our heads a little on this one... We did add a background color to the actual <a> tags in the navigation, and on the devices, the full area was colored -- which means the links weren't collapsed...
