I have a 42 inch LG OLED evo AI C4 4K Smart TV 2024 with a USE6S soundbar connected via HDMI.
Up until a few days ago, the iPhone app was connected via WiFi. I could use it to control the sound effect.
The sound bar remote could also change the sound effect, and the volume with the volume control visible on the TV screen.
Now the iPhone app does not connect to the soundbar and the remote control doesn't appear to alter the volums: there's no on screen display.
And also, the TV WOWcast output is not 'sticky': that it to say I can select it, and it remains for a time, but drops.
