Managed Wallpaper iOS not applying

Question

Hello, 
 We just purchase iPad Pro with iOS 11.4 and we are trying Sophos Mobile to managed them. But when I tried to setup managed wallpaper nothing is happening, I also set the restrictions so that the users cannot change the wallpaper but they still can. 
 The iPad appeared as managed and compliant, other configuration as email setup went ok on the iPad. Am I missing something ? 
 Thanks in advance for your help

has the ipad been supervised\prepared via apple configurator on a MAC or enrolled via DEP? 
 you can only apply wallpaper to a supervised device. 
 this also applies to wallpaper restrictions, the devices need to be supervised. look to the right on each config screen for profiles, if it says supervised then they need to be supervised to apply to the device.

when they are enrolled via DEP then they will only become supervised once they are factory reset.

Hello Jo&euml;lle BLONDEL, 
 
 with the Apple Configurator you can bring your device in the supervised mode too. 
 
 Maybe its interessting for your existing devices. But if you do that, your device will be reset to factory settings!!
