"iCloud Backup" message won't go away & locks the screen.
My ipad has a box that pops up and says "iCloud Backup This ipad has not been backed up for 2 weeks. Backups happen when this ipad is plugged in,locked and connected to Wi-Fi." I repeatedly hit the OK button, but the box still remains. I can't get into any other screen. Please help! Your advice is much appreciated.
