White oval in lock screen taskbar
recently my iPad air, running iOS 12.1 began displaying a white circle/oval in the task bar, but only in the lock screen. I have searched high and low, but found nothing mentioning it. Pressing all buttons I could think of, aircraft mode makes it go away, but disabling it again sees the circle return. I’ve never had this issue before, and have owned the iPad since new, about 4 years ago.eboot did nothing, as that was first thought...
Any thoughts?
