Manage Network Visibility for Desktop and Mobile
With the device visibility, you can easily deactivate the display of a social network on a desktop or mobile device. That option is will save you time setting up a different list for mobile devices.
The option is globally applied to all instances for the displayed share buttons. To activate it visit Social Sharing ->Networks and press the manage button next to the section.
On the new screen just activate the option and choose which networks should be hidden on the desktop and which on mobile. If the buttons should appear on any device just don’t touch the settings.
