Works for me too - only thing I noticed was that Bloom and Glare do not show up (for me) during rendering or denoising, in either LightMix or Beauty, but once rendering and denoising is complete (or denoising is cancelled), it shows up in both.
While it IS set in the version of the scene you sent, just a note that LightMix does have a checkbox on whether to enable bloom and glare, in case that was somehow turned off in your own tests.
