Magic Keyboard Trackpad cursor disappears.
It does not happen a lot, but occasionally the trackpad cursor on the screen disappears after some usage. There have been some tips to do some fancy removal of the iPad, close the keyboard and then open it and put back the iPad, but that did not work for me.
The only solution is to shutdown the iPad, and then restart (reboot).
I use my iPad and Magic Keyboard a lot - minimum 6 hours a day, up to 12, average 8 (continuously). And this happens at least twice a week.
