Yes, I just bought a 2021 GMC Denali 1 ton with the Smart Trailering on it. We just bought a 5th wheel and put Furrion Cameras on it and the same thing happened. I called Furrion when I ran my generator and put a device i use to check the trailer lights by connecting it to the 7 pin connector and what do you know all the cameras came on so I figured it can't be the cameras or the trailer. I came on line and asked the question and this site popped up! I was glad to find out the problem but, they told me that they have an adapter for 2020 GMC but are still working on 2021, so I'm out of luck for now unless someone knows any other company or way to connect.
