I have a nice WiFi streaming amp and 2 new iphones. Pandora randomly stops 30 minutes to 2.5 hours. I have to restart the app when this happens. I have friends with android phones that stream Spotify to the amp and never have issues with streaming. There are 2 options on the Pandora app to stream to the amps; Airplay and Chromecast. It is a Ubiquiti WiFi system. I have talked with both Ubiquiti and the VSSL streaming amp tech support. I am starting to think it is a setting on the phone or app itself. Any ideas for a fix would be greatly appreciated.
