Is it me, or is anyone else seeing a pattern here ?

seems to be a design fault. 

hi John b, hope you’re well 

@dp laing What are you using to charge the Roam with? Can you turn on the Roam? Does the Sonos app see it on your system?

Try rebooting the Roam following these steps:

1. Disconnect Roam from charging cables and remove it from wireless chargers.
2. Hold the button on the back of Roam for at least five seconds until you hear the power-off tone and the light above the Sonos logo turns off.
3. Wait 10 seconds.
4. Press the button on the back of Roam to turn it back on.
