That "Controls" page is for controlling things like UConnect Theatre if its installed. I have the same blank page on my MY2021. But I also don't have UConnect Theatre. I'm guessing you don't as well. If you also don't have the SOS button on the rear view mirror you probably don't have the Telematics box installed on the vehicle. If that's the case you won't have access to any UConnect online services or SiriusXM Guardian. Chrysler has been removing that functionality from a lot of vehicles probably due to the semiconductor shortage. Check your window sticker and see if you see anything deleted and a credit applied.
