I have the latest HA and a 2019 LG E9. When I try and send say a DOWN key to the TV, it works but always goes down two steps and not one. This is the same for all the arrow keys. It looks like two key presses are being sent out.
Has anyone else experienced this or can shed some light on what is happening?
Solved:
Really Weird. I removed the Latest Version Component from Configuration.yaml and it has started working properly again.
