My Ultra has now received this update, without any notification of an update being available, or any user intervention from myself, and I have been checking many times each day since it was announced here.

Just got it too. Really hoping this fixes my Tidal Connect issue where the queue just stops after a while (1 hour as per the release notes?) and from that point on will only play one track at a time until I choose something else to play.

It gave me an excuse to spend a couple of hours on Sunday tranferring all my 'likes' to Spotify, but the spotify connect / chromecast situation is a pain there too.
Do I need to consider going back to Qobuz?
