Opened a case today, 19-Jun-2021, with LG support. Some additional information:
- My setup: internet <- cat5 -> Roku Ultra HDR 4K UHD <- HDMI -> Denon AVR-S960H <- HDMI -> LG OLED
- I'd recommend using LG chat. Email results in typical "reset this, reset that". You'll need model and serial number of TV. Email response from LG stated that chat is only open M-F. but someone did respond today (Saturday). Open cases!
- I had the LG rep add the link to this thread to the escalation ticket.
