Gapless playback issues after 15.2 update

Hi

I am having issue described with gapless music via Apple Music.  I listen to a lot of dj mixes and can clearly hear there is a gap when it goes from one track to another.  Happens when I have spatial settings on and listening to Dolby atmos mix.  I am running version 16.2 with latest Sonos app via Era 300.  If I disable spatial music via settings everything is ok.

Quick update, made a mistake.  It is also happening if I have spatial disabled.  Any gapless dj mix I play has a small noticeable gap.  I have tried with wifi plus Ethernet connection and same issue

So… Now I’m having the opposite problem. The next song is playing too quickly, and the beat is off with DJ mixes. It’s like Sonos engineers decided to “build in” a slight crossfade to resolve the issue. Uhm… 

  I clearly hear a track transition glitch when playing Dolby Atmos tracks either from Apple Music or Amazon Music.  Even when playing Atmos music with Amazon Music on a Fire Stick 4K +.  So this is on Sonos.  These glitches are most noticeable when the track change is during a loud passage.  

 The system is Arc - Sub - 300s.  In all cases the playback is reported to be Atmos.

 This glitch is very distracting!
