My best guess is that the B&O app and the M5 has beenupgraded to support Deezer HiFi, but that other devices have not yet had thesoftware update to support this. People testingthe beta Moment software say it supports Deezer HiFi, so I believe Deezer HiFisupport is coming in the next software update. The question I have is whether DeezerHiFi support will be coming to the essence Mk2, BeoSound 35, and Avant Mk1. It is possible the devices support DeezerHiFi, and all that is missing is the indication that FLAC is playing.
