Since the new "improved" app (designed by someone with no technical knowledge whatsoever) my Sonos products cut out endlessly and or between rooms as well. It's not my wifi as I have 3 different Sonos accounts in different locations and they all do the same. One on my boat, Sonos 1 at a house and Sonos at main residence. (1st world problem I know) BUT it just isn't good enough when I've invested £1000s in kit. 

On boat cuts out every minute or switched between. BEAM AMP OR Roam or One 

At home shifts between upto 6 different zones and or just cuts out. It's utter garbage. When will this be fixed ? Wifi on boat is >50mps

At home it's >300mps
