I cannot get my iPhone or laptop to connect to my Sonos system other than for a few seconds.  On the app and my laptop, only a few of the Sonos devices show up, then they disappear and rarely will anything play.  I have unplugged the devices but no luck.  Additionally, it will not allow me to use Apple Music.  Seems like the whole system is just totally screwed up.  I have repeatedly tried to update the app but to no avail.  Any help would be very much appreciated.
