Spot in France : why is it so deaf???

[LeKeiser]

Hello,

Compared to my Echos and my Show and my Homes and my Mini, my 2 Spots are quite deaf... It seems they are so deep asleep that it takes 2 or 3 "Alexa/Amazon" to wake them up 
And they don't seem to like being called "Echo", they hardly reply when I call them this way. "Amazon" is a bit better, but a tiny bit. They prefer "Alexa" but I have to call one of my Spot "Amazon" because it shares a room with an Echo, so...

Hope Amazon can do something about that deafness...
