In the Desktop UI, if there are more modules than fit on the screen, the screen does not allow scrolling down to view more modules. In the mobile UI, you are able to scroll up & down when there are more modules than fit on the screen. In the “All Devices” view, most of the modules are therefore off the screen and not accessible/visible.
I am using OS X 10.11.4 and the desktop client version 6.32.18
thanks
