      Picked up Diesel Yukon on February 27th. It has been great.

      Just connected travel trailer for first time. Trailer detected and I created trailer profile.

      Brake gain info screen however shows nothing. Either with pressing brakes or sliding lever. This worked with my previous 2019 Sierra. Trailer connection is clean. Tried disconnecting reconnecting several times.

      Anyone have ideas?
