I played my world yesterday with my friends and I stopped playing it and got an update so i updated my game and 80% of my worlds are broken they keep saying the same thing such as Failed to Sync world data. Could not sync your world data. Would you like to try again? I have been trying again and again I have deleted Minecraft restarted my xbox restarted Minecraft and same thing . I even switched minecraft from my xbox to my stroage drive and back to my xbox nothing has worked.
