Using the Deco M3 + Range extenders in a 2,500 sq foot home, my wife's Android watch does not receive messages/calls/emails from her Android phone when the phone is in one room, and she's moving around the house where there are other extenders.  Both the watch and the phone are connected to the Deco wifi network.  

I do not have this issue with iPhone & Apple Watch when both are connected to wifi.  Am I missing something in settings that would allow Android to seamlessly communicate between watch & phone so that she doesn't have to carry her phone with her from room to room when switching between extenders over wifi to get communications on her watch?
