Disconnects from Chromecast. I have a speaker group with two Google Home Hubs and one Chromecast. When playing music, it consistently loses connection with the Chromecast and I'm not able to adjust volume. I can adjust the volume of the hubs (usually), but not the Chromecast. The Chromecast continues to play music, though. Also, I'm not able to adjust the group volume using my Pixel 3a's volume buttons on the side of the phone. That feature used to work quite well, but not it rarely works.
