I have an android phone, so does my partner, I randomly got a notification earlier saying xxxxx is on Duo. He says he's never used it (I thought I hadn't either but it is logged in on my phone with 1 video call in 2018!) So is this a random notification trying to get people using it or does it mean he is on it & using it? As I said, I had a new Samsung earlier this year, certainly haven't ever used it on this phone but it does clearly think I am to be getting a notification. Thanks
