One note here. I have a 2018 with factory RSE. I have had both screens and the coax cable replaced, and I still have intermittent issues. EVERYTIME my passenger/slave display doesn’t work, you can turn it on and control the display with the Lincoln Play app. It doesn’t solve the greater problems, but using that app has saved me from pulling over, moving the passenger seat forward, and restarting the vehicle. I have no idea how or why the app can control it when the buttons that are physically installed cannot, but it works.
