I have Sony KD-55X8500G TV, But i amazed this 2019 model TV has Not capability to recording TV programs and Screen-Mirroring. (most old cheap TVs have this features) How enable this features?
Also i updated the TV to latest version (Android 9)
TVs for the US market have never have the ability to record. Some TVs for other markets do but it's not a universal feature.
Content providers want to give or sell you that function as part of their app or service.
The TV does seem to support Chromecast so screen mirroring should be easy enough.
