Ramsey property for finite dyadic measure algebras

Determine whether the class of naturally ordered finite dyadic measure algebras is Ramsey, equivalently whether the corresponding homogeneous dual Ramsey theorem for equipartitions holds.

Background

The problem concerns finite Boolean algebras equipped with dyadic probability measures and natural orders. A positive solution would yield the structural Ramsey statement identified as relevant to extreme amenability of automorphism groups of standard probability spaces.

References

To our best knowledge, all these Ramsey-theoretic statements are still open.
