Latest Xbox Update (Xbox Series X) HDMI-CEC Broken

Firstly, please let me know if I need to call support to make them aware of this problem.

Since the last update I've been fighting with my Xbox Series X turning on my AV receiver and TV no problem, but failing to shut them down... I've done some testing and looks like I've verified that the console no longer sends the turn off signal when it shuts off.

I've been able to get it to work by switching the power settings from instant on to energy saving and vice versa, but after switching it only works ONCE. Then after that it never sends the signal again.

Please fix this!

:)
