Its stable on the Admin range, not on Curric. But I take your point, it was working before the summer break. I suspect that BTLS are tinkering with the settings but not bothering to let anyone know. I use Apple Configurator to deploy to the IPads so I connected the IMac to Admin and everything worked wonderfully. IOS 8 is due out tomorrow, now how are you supposed to cope with intermittent access for a full upgrade!
