I have the same issue with mobile devices.I've checked all the settings and everything looks right, but it won't sync.I managed to solve it by removing Kaspersky from the device and installing it again.One message that might be relevant is 'Cannot find the device on the Administration Server.'when I try to sync through the Admin Center.
