Hi, I have an Echo and several Dots. They have been working fine until recently. Sometimes when I ask Alexa something, her response cuts in and out. Note this does not appear to be Bluetooth-related since the devices are using their own speakers. Also, as an additional clue (maybe), it doesn't appear to be WiFi-related either, because I can stream music flawlessly without any cutouts. It only happens sometimes, when Alexa is speaking.
