After weeks of rumors that the feature would be coming, Google Duo has finally added the ability to use the video chat app across multiple devices. The new feature is a combination of an app update as well as a cloud-side update from Google to enable it.
First, you need to make sure you have the latest version of the app. That was released yesterday and is build 36.1.202022753.DR36_RC15 for those keeping score at home and who like playing Google Version BINGO! Once you have this version, you will shortly thereafter get a cloud-side push from Google. You will know that you have received that Google update when you are prompted in Duo if you want to use your Gmail address instead of your phone number to sign into Google Duo. That is key because that’s how multi-device support works in the app.
