Local-to-global cyclic polymorphism conjecture for omega-categorical cores

Let ${\mathfrak B}$ be a countable $\omega$-categorical model-complete core, and let $f$ be an $n$-ary polymorphism of ${\mathfrak B}$. Cyclic polymorphism conjecture. If, for every finite subset $A$ of the domain of ${\mathfrak B}$, there is an endomorphism $e$ satisfying $f(x_1,\dots,x_n)=e(f(x_2,\dots,x_n,x_1))$ for all $x_1,\dots,x_n\in A$, then ${\mathfrak B}$ has a cyclic polymorphism modulo an endomorphism. The source does not state whether this local-to-global principle has been resolved.
