Smite 2 is now available for players with the Founder’s Edition following the launch of the 24/7 closed alpha test. Issues are expected as the game is still in development, and the version mismatch error can cause problems.
While the devs will fix many bugs and errors during development, the Smite 2 version mismatch error is not a bug. Instead, it’s the game’s way of informing you there’s an issue with the version of Smite 2 you are trying to play.
