BLUF: Sony TV firmware version [v6.7140] does not turn off using the Apple TV since November 2020.
The latest as of 13 FEB 2021 is an update from Sony from a month ago (13 JAN 2021) stating Sony is aware of the issue and working on a solution. In most production environments it is commonplace to roll-back, if that is not possible, could Sony also consider releasing an updated firmware with prior version [v6.6575] that worked properly?
