I have Sonos Play 5 that is wired and Play 1 that uses Wifi. Spotify is skipping songs. Sometimes every song skips, and sometimes one, two songs play fine until next song skips after 30s - 2 minutes. I have tried to change wifi channels but the problem still continues on 1, 6 and 11. I have a 50 mbit internet connection and Airport extreme AC router. I have sent a diagnostics report with number 3956286.
