When I open the S2 app on my iPhone, iPad or iMac the rooms appear within seconds. However, when I browse to Apple Music or Amazon Music the artists, albums or tracks take 15 to 20 seconds to load (each time). Therefore, selecting an artist, then an album and then a track can take up to a minute!!! Playback seems fine though. My internet speed is 25-30 Meg. I have my router on channel 1 and Sonosnet on channel 6. I have a Sonos Boost hard wired to my router. Any help would be appreciated, as I’m considering going back to S1, but I believe this will mean recreating my system (and I have 13 components!).
