I’ve made some changes to my controller.
Is there a way to reset my controller back to all of its default settings?
In controls options - choose the controller profile at the top, click to select “Default” that will be how it was originally, the default cannot be altered or saved so will always be there 
Has the default Xbox controller mapping changed since the first release? When I reset it, it’s not the same mappings as in posts I’ve seen here and there on the internet.
