Hi all. Using an iPad Air with iOS 7.1.2. I want to set the Auto-Lock timer to Never, however it is only giving me the option set this at 2 minutes or 5 minutes, that's it. I have tried turning off the Passcode but it will not let me (it is greyed out). Also Require Passcode will also only give me the options of 1 minute or 5 minutes. I want to be able to leave an app (Sonos music player) running and displayed on the screen and the iPad would be connected to the mains at the time. Any suggestions please?
