I have 39 iPads Air (WIFI) iOS 11.2.6 was reinstalling using iTunes.
App on guitded access, display auto-lock - never, do not disturd - on, notifications - never
Sometimes the screen is blocked randomly on one of the iPad
on iOS 10 there was no problem.
this happens after receiving a message from apple "find out what's new in iOS 11"
