Ok so more that I use AR more it breaks down. Now AR seems like it is running just fine but no audio is still passed to my Home minis. Stopped suddenly and I get no errors. All minis are online and working normally, AR makes POST but nothing comes out.
EDIT: Did some testing with sandbox and sometimes POST goes to all google home devices, sometimes just one of them, sometimes none of them. This is weird. Also noticed that there was another topic where users said that Google integration has some problems.
Not sure if it has anything to do with this but fyi. I remember when I used Amazon echos (EchoSpeaks) and Amazon decided to limit how many announcements can be sent to Echo devices. This feels exactly same problem but there should be no limitations right?
