Lots of drop outs over the last week since adding a SONOS ONE to my Playbase,Connect,Connect AMP,Play3 and 4 play1 system. Playing spotify with all grouped , turn on SKY box for TV sound on PLaybase leaves group fine but all the other playing speakers stop !!! . Really slow for all speakers to come up to spotify ..Alexa on ONE comes up but takes minutes for the others in the group to activate . Also lots of speak drop outs which I have never experienced in running SONOS. Had to move from Apple Music to SPOTIFY because on lack of ALEXA support on Apple.
