I have two houses full of SONOS products (61 in all..about 30 in each house).  When I select My group of speakers and play music, it takes too long for all of them to start playing music.  I feel the speed should be faster, smoother.   I got The same thing if I am using the same group and change the music.  If I select 10 speakers at once...it may take 20-30 seconds for them all to turn on. Yes..I know this is not an earth shattering problem like global warming and I’m being picky. But I wish The connectivity was better.  I use a boost at both houses and have high speed fiber. Both houses are around 5800 sq feet in size.  Not sure what else to share to help diagnose the problem.  Maybe we need Sonos to make a better boost?  Idk.  Thanks!!!
