Can you untick this auto-KERS with Live Viewer? Or do I need to subscribe to stop my drivers using all their KERS?
Theoretically, yes, but there's an issue with that.
I had the unauthorized KERS issue a couple of races ago, and when I had it, I was able to determine that if the viewer ticks the Driver KERS checkbox on its own in the Settings, the driver still does not have control. If you click to clear the checkbox,
the option actually enables. The control works backwards when the viewer glitches: checked is
disabled and unchecked is
enabled. Reloading the page (and thus the viewer) resets the behaviour to normal. (The reload forces the viewer to request your settings from the server.)
As I understand it, both the Live Viewer and 2D Viewer have this issue.
