It's indeed the new app but not yet ready for multiroom, app is still in beta form. Full Multiroom and DLNA possibilities are expected at earliest in March.
'We will be adding DLNA playback in an upcoming update, which will be released around March 2017. Basic support for TVs is also planned in a later update, however there are currently no plans to add support for the NL/ML converter.'
"Believe nothing you read and only half of what you see, let your ears tell you the truth."
App looks great! Hope B&O finds a army of developers to get this up-and-running.
