I could say something to my Google Home speaker at a low volume in one room, but frequently a different device in another room will answer me or execute the command I gave.
For example, I used to be able to tell my bathroom speaker to play music with no problem. But now instead of playing the music from the bathroom speaker I gave the command to, it will send the command to my TV in a different part of the house and play the music there. Having to repeat these commands multiple times on top of power cycling the devices makes for a very frustrating experience.
