This is the reply from Cisco Meraki Technical Support.
"I performed tests and reached out internally to double-check the expected behaviour. It turns out that these commands are currently not available for Android devices (they are for desktop devices (Mac OS X, Windows), and for iOS supervised devices only).
I also checked if there was any plans of impementing this shortly, but it's not the case at the moment. I suggest using the "Make a Wish" button located at the bottom of your dashboard. This will go straight through to our Product Development team, and if enough people wish for something, it will get pushed higher up the development schedule. "
A pity that this functionality is not available for Androids. Please "Make a wish" as recommended, if you need the functionality.
