Lock/ unlock switch gone
I Upgraded to iOs9.1 this morning. After installing I noticed that the lock button or "wake/ sleep" button wasn't working anymore. I can still take screenshots and power down the iPad if needed. Before in the past when I've experienced this problem there was a button in the General settings for a lock/unlock switch. That is no longer there. Even under the assistive touch the locking and unlocking doesn't work. Where did the switch go???
