What's the correct procedure to supervise iPads running iOS 8 using Apple Configurator?

[vmr309]

When I update the iOS on new iPads to 8.0.2 and connect to my mac mini running Apple Configurator, it errors out while supervising the device (Prepare). Happened with 3 devices and all I get is connect to iTunes symbol. And when its connected, the restoration fails. (Replaced 1 iPad already)
Is there something I'm missing here? Worked fine with all old iPads prior iOS 8.

What version of Configurator are you using?
