So, apparently my LG TV (G3 Evo) was updated today or yesterday. Since then, I have been unable to send notifications to it, and some custom pyscripts I have to change brightness and backlight settings are not functionning either. It’s not a connection problem, because I am able to turn the screen on/off in the pyscript, and am able to mute/unmute on the media_player device.
My guess is that the update broke the API somehow, but I can’t be sure, so I wonder if anyone had similar issues in the last few days.
