I have major issues with Spotify Connect from my IPhone, Samsung S6 and IPad with my receiver Pioneer SC-LX79. AirPlay works fine, but if try to use Spotify Connect it doesn't work. Spotify client find my receiver but i'm not able to connect and play. I've open port 4070 on my router but it doesn't help. The problem started a week ago.
