FireHD8 tablet (UNregistered) running free FullyKiosk and ActionTiles. Within the last week or so, the tablet has suddenly started showing Ads on the lockscreen. It has never done this before - and is the reason the tablet is UNregistered. I didn't change anything or install anything new. It did it on it's own. Yes, auto updates are turned on. Did Amazon push something out that changed the lock screen for unregistered tablets?
