Trouble starting a Split-Screen game

Hello,

I’m playing Forza Motorsport 7 on my Xbox One Console.

Lately, when I try to initiate a split-screen game witha second controller, I cannot get the second player to join.

Once I enter the SPLIT SCREEN menu, the lower right hand corner indicates to press the “=” button on the second controller to join the split screen.

The problem is that when I press the proper button on the second controller - which is already logged in and can play other single-player games - nothing happens.

What am I missing here?

Joe
