The common relative Jacobian conjecture for Type i KSS pairs

Let $(A_i,B_i)$, for $i=1,\ldots,12$, be one of the twelve Type $i$ KSS pairs of smooth elliptic Calabi--Yau $3$-folds over $\mathbb{P}^2$, with elliptic fibrations $f_i\colon A_i\to\mathbb{P}^2$ and $g_i\colon B_i\to\mathbb{P}^2$. A relative Jacobian is the relative elliptic fibration associated to an elliptic fibration. Common relative Jacobian conjecture. The elliptic fibrations $f_i$ and $g_i$ share the same relative Jacobian $\pi_i\colon J_i\to\mathbb{P}^2$. The paper's abstract states that this claim is proved for every pair, so it is no longer open.
