Also if I were to get realms is it possible to put my world that I cant sync onto my xbox into a 2 player realm? I would be willing to pay to get it back.

I've had a similar issue to the ones mentioned above with my world. Around October when my world size exceeded 100 mega bites, I could no longer sync it between xboxes. At the time I didn't really care since I only played on the xbox I used most but recently my xbox did a factory reset wich meant all my worlds needed to sync again. This meant my world was forever lost because I can't sync it to the xbox or any of its copies that exceeded 100 megabytes. My world reached over 300 megabytes before I lost it meaning i would lose months of progress if i go back to the newest copy that will worked. Please fix this bug because it can take huge chunks of progress from worlds if people aren't careful.

I think I'm having a similar issue to you. My 300 mega bite world is not syncing properly but my 0-100 mega bite worlds are syncing properly. I think it's more of an issue with minecraft than an issue with the xbox 1 s I was playing on because the xbox shows that the world syncs but minecraft brings up a popup saying the world didn't sync fully or was corrupted. Let me know if you are having the same issue as me so I know to create a new report or not. Thanks, have a great day.

Is it specifically for large world sizes? Or is it just for all worlds? For me, my 300 mega bite world won't sync but my worlds with smaller sizes will.
