I bought one of the earliest Echos. It has worked well until about a month ago, when it started connecting to the Alexa app sporadically. For the last 10 days, it has never connected. Alexa does not show up on Bluetooth, even when I search. The app just has the little scanning wheel spinning away, nothing else. Alexa has been responding to voice commands. I have uninstalled, and reinstalled the Alexa app, three times. Finally, I pushed the Echo reset button. Alexa has been asking me to follow the set up instructions, but there is nothing there, except for the little spinning wheel.
