Odd, can you post a screen cap?

Sonos makes Era named speakers, the Era 100 and the Era 300, and play is a function to deal with music, but I’ve never seen the two smushed together without a space before. 

Which windows app are you using, the Web app, or the Windows app? Are you on S1 or S2? Which speakers are you playing to?

Thanks for your reply Bruce

Actually I am wrong. It is on my S2 IOS app

Apologies. Old age lol

So I understand Everywhere and All, although are they not the same thing?

But does ERAPlay only play on my two ERA300

It does not seem to do anything

I suspect, with no evidence at all, that at some point, you created a ‘named group’ called Eraplay. Go to settings (the gear icon on the top left), and then select Manage, then Groups. See if Eraplay appears there. 

Spot on. Thank you.

Sorry for wasting your time.

Shows you how much of the app I use
