WB didn't even decide to finish the Snyder Cut until after Aquaman, Shazam!, Birds of Prey, and WW84 had been completed, so naturally those movies were consistent with the theatrical version instead
As has already been mentioned twice, James Wan explicitly stated that the released version of Aquaman was consistent with Snyder's version of JL, not the theatrical cut, and did so either shortly before or shortly after Aquaman's release.
The explicit references in The Flash to events that only occurred in Snyder's version of JL is further evidence/confirmation that, despite WB's public claims otherwise, the MoSSCU did not in fact become disconnected from Snyder and his influence vis a vis the theatrical cut of JL and Joss Whedon's script changes.
