Bluesound recent update 4.0 tanked sound quality ???

My streaming subscriptions are with Amazon Music and Sirius XM.

I took the upgrade yesterday and haven't noticed any change in SQ but will be more observant today.

Not to go too far off topic, but I'm disappointed in the lack of basic functionality enhancements in the BluOS Controller App for Windows.
 

I have a Node 2i/Ares II in one system and a Powernode in a second system.  I've noticed no change in audio quality with the update.  I stream Qobuz, Tidal and FLAC files from a NAS drive.

The update went smoothly for me, although the interwebs say a lot of folks had issues.  I like the new UI; it is more intuitive and looks better on the smaller screen of an iPhone.

(Of course, Qobuz went down on Oct. 18th for a short while and drove the BluOS world crazy).

Did the update on my iPad a couple of days ago and hear no difference in the audio quality through Bel Canto DAC and amp and Q Acoustics speakers. The interface is a nice improvement..

I use a Node 2i and and external DAC. I notice no difference in the sound. New interface seems better and still getting used to it. I updated both the Node and the IOs apps.

Node 2i into external dac. Downloaded update yesterday. I only use for local classical radio station and Tidal. I have noticed no change in sq.
