Hi Sonos world 

I have a Sonos one and a Sonos Beam

i don’t use the app very often, maybe to tweak the sound but usually I use Alexa on the “one” to access music.

everything has been fine for years, until..

several weeks ago I used the app to change a setting on the Beam and noticed it wasn’t showing in the app. I closed the app, re opened it and boom!

there it is, except 

now the “one” isn’t showing in the app 

So I turned off both products and turned them back on and still only one shows on the app at anyone time. The app is upto date and trying to add a new product doesn’t work. 
ti get the ‘one” to appear I have to turn off the beam and reboot the app

anyone had this or can offer a solution ?

Thank you
