I have a Spotify premium account. For the past year Spotify Connect recognized my Yamaha Wireless amp on any device (Android, Ipad, etc). Now Spotify does not recognize the wireless amp on any device. I have rebooted the amp (including hard reset), insured it is operating under the latest firmware, updated the Spotify amp, and insured that the amp and spotify account are operating on the same wireless network. Still it is not recognized. Any help would be appreciated.
