Recently received a 2024 Yukon Denali Ultimate. During the sales demonstration of the vehicle in Demo mode, the rear media panels displayed source options: HDMI1, HDMI2, YouTube, and Hulu. Now that the vehicle is at home, the back displays display just HDMI1 and HDMI2. YouTube and Hulu are no longer available. We contacted tech support via Onstar and were disconnected. Additionally, we have engaged in two chats on the GM website, although no one seems to own the solution to this issue. Has anybody encountered and resolved this issue? Thank you!
