I’m using a 3rd gen iPAD PRO 12.9. It has been pretty flawless since purchase (new) back in 2018. Over the last two months I have had a strange action when in jiggle mode. It happens when I click on an app icon too fast and move the cursor at the same time. I get the little (-) in the white circle but when i click on ”done” at top of screen or just click on the screen to stop jiggle the (-) stays on the screen but behind the app icon and still jiggling. I actually have 2 of the same icon stacked on top of each other. The one in the rear is still jiggling. I’ve tried dragging the top icon to another part of the screen but it returns to the original spot and the icon in the rear keeps jiggling. A restart clears it but I’m concerned something major is about to happen to my iPad. Attached photo shows a still shot of semi-hidden behind the “Healthough” folder
