the frequently used apps page when set for 4 columns, 5 rows, only displays 17 apps instead of 20.
On my Sony Xperia XZ (5.2"), I've set frequently used apps to the full size of the screen, with the exception of the 1 row the dock takes up. It has been set for a 4 column, 5 row configuration. however, it only displays 17 icons, stopping at the 5th row, 1st column. The other 3 spots are simply empty. I've set my icon/font size one step up from default.
if I change the config to a 4x4, all 16 apps are displayed. but going larger than 4x5, it stops at 17.
further, any configuration past 5 rows doesn't render, either - and still only 17 apps display.
