I had a customer come in with a 2020 x7 asking for help with setting up screen mirroring, so I started to set it up and he was paying for the Wi-Fi and had Bluetooth and apps hooked up As well, I'm not to sure as to why I couldn't get any of the screen mirroring apps to cast to his rear seat entertainment screens, now that I think of it it could be a privacy setting but any ideas out there to which app to try or what apps worked for anyone else? Thanks in advance
