I have 3 era 300’s which stopped working 60 days ago. I have factory reset them hundreds of times , tried to delete the system , create a new account , etc , etc . Why is this so hard ? Why does sonos sort of manage my system ? I should be able to delete speakers , accounts , etc from the web and app. I feel like big brother will not let these speakers roll onto a new system. I hate sonos ….bigtime
