Ok, I've read issues like this in which Denon receiver can't connect, the thing here is that my Echo Dot can connect with no problem to the receiver. But my new Echo (2nd generation) can't. It shows in the list, it "pairs" but no confirmation by Echo and the reciever says "no connection". Then, if I say "Alexa, connect to speakers", the reciever sometimes disappears from the paired devices list. Any insight I can use?, Already tried solutions on the Echo page, reinstalled the Alexa app, forget devices from the Echo Dot.
