sonos app update sucks!
i recently updated sonos app on iphone (running whatever software is before ios11). now sonos will recognize speakers (i have six sonos play:1s around my home) one day and not recognize them another. when playing music it will sporadically cut out for 8-10 seconds. system was working fine with none of these issues before app update! what am i supposed to do to fix? is it possible to re-download older app version?
