Did you pick Let Windows Decide or Best appearance first - apply and test?
Then whittle down - that's how I ended up with the ones I posted in the screen shot - but .... they were the same custom ones I had before selecting let windows decide ....
I spoke too soon.-edit1
The snap worked until I shut the VM down and came back to it later.
When I started the VM and logged on - snap did NOT work until I set visuals to Let Windows decide.
I'll shut down and see if it sticks, then I'll try whittling down the visual options again with VM shutdown in between
Let Windows decide visual options
untick the top few and restarted the VM
Unitick all but the ones in my previous screen shot
ticked two suspects and snap worked
restarted the VM
Snap still worked
unticked show Windows Content while dragging and snap stopped working
ticked it back on - snap worked - restarted - snap worked
but.... the windows don't minimize to the previous size - they keep the snap size
I can manually resize them but they don't snap back after snapping.
Who knows by Wednesday I might not have snap anymore - I'll start playing with the vertical snap while the horizontal is working.
