I updated my LG SM85 to v03.60.19 yesterday but it did not seem to do anything. Today Airplay and HomeKit are working on my iPhone (iOS 12.3.1) and macOS Mojave (maybe started working after turning the TV on/off).
Airplay is fine, but HomeKit is not much use, no volume control and can only turn the TV off, but can't turn it back on since TV does not respond. There is a setting via Homekit which appears on the TV, to allow it to turn on via either Wifi or Bluetooth (both on), but makes no difference.
