I have a Alexa Sonos system at my primary house. I purchased a Alexa beam for my secondary house. At the second house, the Sonos will only work if I manually select music from my phone on the Sonos app. If I ask Alexa to say " Play Pandora Rock Station" Alexa says, " You must activate this on your phone". It is activated on my phone, as I have used my Alexa Sonos system at my primary house. I spent an hour on the phone with Amazon and got nowhere. The said to ask Sonos. The problem seems to be with Alexa interfacing with Sonos at two different locationsl.

Are you using the same Sonos and Amazon accounts at both locations? The link between Sonos and Amazon is a 1 to 1 relationship. When you add the Sonos skill to Alexa, you're asking to provide your Sonos account credentials. If you actually have 2 Sonos accounts, one for your primary house and a second for your secondary house, with only the primary house account linked to Alexa, then no, your Beam at the secondary house would not be setup with Alexa.
Your options really need to be either one Sonos account to one Amazon account shared between both locations, or separate accounts for Sonos and Amazon at the two locations. I'm not 100% sure the former is possible.
Note: You can setup 2 separate Amazon music acocunts associated to one Sonos account in terms of music sources, it's just Alexa control that is a one to one relationhip (pretty sure on this).
