Does not work reverb for Gameplay Audio Volume

Hi all again.
Using UE5.4, trying to follow this tutorial.
On a level, I have a sphere mesh actor with wave asset attached to it, which is looped and matched to new a sound class.
Sound class is set as it said:

  • Route > Apply Ambient Volumes - checked
  • Submix:
    • Send to Master Reverb Submix - checked
    • Default 2DReverb Send Amout - 1.0

Creating AudioGameplayVolume, scale it to be big and overlap sphere with wave asset playing. Attach reverb to it, let’s say, Cave prestet, volume - 1.0. fade time - 0.0.
Next to it, place simple AudioVolume with the same reverb preset - Cave.
Press Play - if I enter AudioVolume - reverb is applied, if I leave it and pass into GameplayAduioVolume - reverb does not work. What’s wrong or what have I missed?
