Hello All! I seem to encounter a problem with the guided access application on the iPad. All of a sudden, the feature turned on and it has left an annoying sign on my iPad screen: "Guided access app unavailable. Please contact your administrator". I turned off guided access but the sign still remains. I have tried a force reboots and regular shutdowns but guided access always seems to turn on by itself and the annoying sign always seems to remain. Urgent help needed!
