I cannot sign in to multiple profiles using the Legacy Game Controller Adapter in Rock Band

The Xbox One console recognizes the Legacy Game Controller Adapter as a single controller. Because of this, only one profile can be signed in when using legacy instruments connected through the adapter.

All connected legacy instruments will use the same signed-in profile. This behavior cannot be changed.

Rock Band 4 controllers can still sign in to different profiles as expected when not using the adapter.

1. Close Rock Band 4.
2. Sign in to the profile you want to use on your console.
3. Restart Rock Band 4.

Starting the game after signing in helps prevent issues when switching profiles during gameplay.

Note: Switching profiles while the game is already running may cause unexpected behavior when using the Legacy Game Controller Adapter.
