I’m having issues with a Sonos speaker pair constantly dropping from my system. After powering on/off they connect and show again, but as soon as I use them as part of a group of speakers they disappear again. These speakers showed for the past 2 years but since the latest major app release they have gone awol. I have rebooted router etc and issue remains. I’m assuming it is a network issue still

I want to check my Boost connection - how do I know that the speakers are definitely connecting to the Boost?

With the new app version I can’t locate the connection method WM:2 

(see below link for instructions for the prev version of the app)

Thanks in advance
