So before my Google Assistant worked beautifully with my Bravia TV, either from one of my speakers or my phone. I was able to use voice commands to turn on/off, cast YouTube & YouTube TV, control volume, etc. Then about a week ago I noticed a issue where now with the exception of turning on/off I am now getting the "Something went wrong" when I try to give a voice command to control the tv. I am still able to cast from my phone but having voice commands was really nice. Browsing the forums it appears others are experiencing this? Is Sony/Google aware? Is there a fix coming?? FWIW still on Android P.
Although I don't have a Sony, I am having the same issue. So I think this is a much wider problem.
