This is specific to the iPad. I’m running an iPad Pro iOS 11.1.1 Auto-lock options are 2,5,10,15 minutes. On my device only 2 minutes works. The rest do nothing. Things I’ve tried.. Soft reset Reboot Read that low power mode can cause this. iPad does not have a low power mode so this can’t be done. Read that turning off passcode and rebooting can fix this. Can’t turn off passcode due to an exchange account forbidding this. Read that accessibility/assistive touch can prevent this. It’s set to off. Anybody got other ideas? To confirm 2 minutes works but nothing else. --- Post Merged, Nov 14, 2017 --- Also noticed a couple of other things. Auto-lock only works on the home screen and never when ANY app is in view.
