I'm having the same problem. So frustrating! When I click on the My Station ellipses the only option I have is "Remove from My Sonos" - no New Station or Edit Station option.
Re the firmware update, from iOS, when I open the Sonos app, there is NO More tab. I can click on Settings and then Check for Updates, which tells me that I'm up to date on everything.
