This is the worst app. To ne honest the company Google have been lazy and sleeping . Their everything glitches nowadays. They are not innovative. They are dumb. Example on this app there is no sense of privacy if ur phone mistakely cast on the device it just gives u a small notification. If the Google software engineers can think about a solution to this problem. They should be fired. The solution can be u link the device by qr code and a timer out system with a notification too.
