In the previous version of the app, I was able to have an account for each of the systems I connected to. Specifically, I have two systems, one at my business and one at home. Now, if I connect one account, the other gets disconnected, so I cannot access all the content.
I would also like to add that it would be ideal to be able to manage all the systems remotely, as is already possible on the newly published web app (at play.sonos.com).
