Camera wont follow pawn when simulating gameplay

On your placed pawn, on its settings, scroll down to Pawn and set Auto Posses Player to Player 0

I am in 3rd person gamemode and I created a pawn blueprint whereupon I have a custom static mesh. I changed the default pawn to be my custom pawn “SpaceShip” (overriding ThirdPersonGameMode), but when I play it in the viewport, I don’t have control over my pawn, I have control over the old default pawn. When I delete the old default pawn and play it, the camera zooms in on the floor somewhere and doesn’t seem to be at all attached to my blueprint. Its also worth noting that I created a camera for my pawn which is obviously not being used. What am I doing wrong?
