Switching between 2D Paper and First-Person

UE4 noobie here: I’m switching between a level with 2D Paper as the game mode and a level with the First person Game mode. The problem I am running in to is the camera does switch to first person, but the controls do not. Instead of turning with the mouse and moving with WASD, I can only strafe and jump.

It’s as if my First_person camera is stuck with my 2D controls. How can I get around this?

Have you got a toggle inside your player controller to handle both types of inputs? the game mode change has nothing to do with changing the controller(which should be handling the input)
