When I cast via the Plex app on my Android phone to my Chromecast, the input delay is terrible (~10+ second).
This is seen when pressing the pause/play button or changing the volume.
The delay seems to have gotten worse over the last few weeks.
This is a really annoying bug since trying to make quick changed can be extremely delayed.
The other day, my wife and I were watching a movie and as a really loud scene started I turned down the volume right away but it took over 10 seconds for the Chromecast to respond… The loud sounds woke up our daughter
