Got a new bug with App icons rearranging themselves.
On the last page of the Home Screen I’ve got, in iPad landscape:
Five app icons in a continuous row from the top left.
The second row is empty.
On the third row I’ve got two app icons right-aligned.
On the fourth and final row I’ve got two app icons almost right-aligned, just one empty icon space to the right of them.
There’s no widgets on this page. I’ve had one icon migrate itself from the fourth row to join the first. After correcting, later I had all the icons from the third and fourth rows join themselves to the first overflowing into the second.
