Just curious if anybody else knows why it’s not working is it an Android 11 or UI glitch? I called her she called me didn’t work it told me my video was visible and when she called me I just saw a little notification bar at the top saying she was calling me. Thanks!
My friend in Chicago just got her S21 Ultra the other day it’s T-Mobile. I don’t use Duo enough but she uses it all the time and said there’s a feature and we tried it with each other it didn’t work. Knock knock feature where you can see who’s calling you before you actually answer the call.
