I haven’t bothered with the video because you’ll just see somebody saying “what?” because they can’t hear me on either doorbell. This is happening on both my Galaxy S10 Plus and my wife’s phone which is a S8. When I first got the doorbells (x2) I was using a Note 9 and was having the same issue. I have noticed that the audio goes through my Bluetooth when I’m watching non live past history videos. As soon as I start a live stream the audio goes to my phone instead of my Bluetooth. I thought that was odd.
