Bose, you guys have dropped the ball. Whomever sits in your R&D team should be held accountable for a continual landslide of buggy and inpoerable firmware & app updates.
Im still battling with the ST adaptor fault you have introduced into my ST 535iii, now the latest app volume slider decides it doesnt want to respond anymore.
Example. Start playing Spotify > add another speaker to the current speaker playing> the master and the zone sliders do nothing.
Ive lost total faith in Bose, i wont be buying anymore, nor will i recomend to myfriends. Adding to this, if these issues continnue to linger with my products i will be considering some legal action based on Australian Consumer Law.
