Multiplayer Error with new UE 5.6 FPS templates

I fixed this easily by following the advice here. After some testing it was pretty simple.
Attached is a screen shot on how to alter the templates to work.

+Create a Game Controller BP.
+Reference the Game Controller in the Game Mode.
+Move the Add Mapping Context over to the controller.

All done, screenshot shows the cleanest version that probably should be in the actual templates going forward.
