The consecutive Davenport constant conjecture for finite groups

Let $G$ be a finite group, and let ${\sf C}(G)$ denote its consecutive Davenport constant, namely the least length $\ell$ such that every sequence of $ell$ elements of $G$ contains a nonempty consecutive product-one subsequence.

Consecutive Davenport constant conjecture. For every finite group $G$, it holds

$${\sf C}(G)=|G|.$$

The equality is established in the source for finite abelian groups and metacyclic groups, as well as for direct products of a finite abelian group with a metacyclic group. The general case remains open.
