speakers keep losing connection

I have soundbar in the living room and individual speakers in my other rooms. Over a year ago, they suddenly just dropped out like losing connection then after a minute or so come back on sometimes to a different song. I used Spotify and mine is a paid subscription and my wifi was working during those episodes. I read some of the conversations posted and this appears to be a constant like this is part of SONOS that customers have to live with. I tried to troubleshoot getting advise from Google and your SONOS website but nothing seems to work. I got so tired now I just gave up. Can’t imagine why a big brand would let this go unattended or put up an update to fix it. I read also many frustrated customers about to throw out their expensive sound system. This is how a successful company heads toward downfall by not listening to the very customers that made them successful. Maybe a hard lesson will reshape them or maybe an acquisition or buyout with new owners firing all the ignorant people there will help.
