My Question or Issue
I have 5 Chromecast devices and two groups. When I put any of the devices in a group, the group appears and works fine but the individual chromecast device becomes missing from the list. I have an additional 4 Chromecast Ultra's for the TV which still appear on the list.
I can play to the missing chromecasts through the Google Home but when I try and control the stream with my app it crashes. Otherwise I have to ungroup the chromecasts from the Google Home app each time I want to pick an individual cast.
