On November 12, 2023, Microsoft will no longer allow unauthorized third-party accessories to be used with its Xbox consoles. This means that if you have a third-party Xbox controller that is not officially licensed by Microsoft, it will no longer work after that date. Microsoft has not explicitly stated why it is making this change, but it is believed that the company is doing so in order to protect its own intellectual property and to ensure that users have a consistent experience with Xbox accessories. No matter what, this sucks for those who have went out and purchased a 3rd party controller.
This change has been met with mixed reactions from the Xbox community. Some gamers are concerned that the change will limit their options for controllers and make it more expensive to buy Xbox accessories. Others are supportive of the change, arguing that it will help to improve the quality and reliability of Xbox accessories.
Here is a link to a Microsoft support article that confirms the change: https://support.xbox.com/en-US/help/family-online-safety/enforcement/unauthorized-controller.
Please note that some third-party controllers may still work after November 12, 2023, but Microsoft is no longer guaranteeing their compatibility. If you are unsure whether or not your third-party controller will work, it is best to contact the manufacturer of the controller.
