In snapped mode, for normal, you should see the grid if you snap the view via the orientation cube. Of course, only if you show the grid.
However, after a while it is not showing anymore. I have to kill nomad (close it from the recent app overview) and start nomad again.
The xy-grid is always shown.
Android 13: Galaxy Tab S7
The first two screenshot show the missing grid - the latter two how it is after a fresh nomad start.
