Found first bug. If you stop a track using the KEF remote pause/play button, the track does stop but the Roon control app generates a “transport: Roon lost control of the audio device”. On the flip side, the pause/play does not play/start a track (nor is there any message).
It would be great if pause/play functionality from the remote would work. A+/DLNA/tidal integration has this ability - both pausing and restarting current track.
Even better would be if previous/next track buttons on the remote worked 
(But they don’t work with A+/DLNA either so not getting my hopes up there).
(Edit: I guess this should have gone into the support group in a different thread - can a moderator move it?)
