You are experiencing someone literally no one else has noticed. Either something on your computer got messed up or perhaps you had a messed up system in the first place and you fixed it somehow or maybe you are just misremembering how things actually were previously and so you think something changed when it didn't. Everyone else in this thread who uses a gamepad has told you nothing has changed on SE's end and yet you keep insisting it has.
Seriously stop blaming SE for your personal issues. If SE made changes to gamepad settings, they would of mentioned it in their patch notes. What kind of nefarious reason do you think SE would be hiding the notes about the changes from us?
