I bought a Beam soundbar a while ago and it was, and has been, fantastic. I then proceeded to install two Era 100s around the house. Apart from the delay issues with the TV connections, it was working fine. A month or so later, one of the Eras disappeared completely from the app. Sonos chat guys helped me through it and I got the Era to reappear but it has always said no connectivity. Went through the motions with Sonos chat and lost interest after 5 hrs of "try this, try that". In the end they were saying that there is no compatibility with my WiFi booster, although it worked fine for a month. Anyone able to help at all?
