I'm using Nintendo Switch.

1. My first realm was expired.
2. I made a new subscription.
3. Download my expired realm.
4. Replace world in my NEW realm(new subs).
5. Failed to upload, crashes the game.
6. A whole day of reupload, archived, uninstall, restart, check for corrupt, no corrupted file, checked internet (i can play other games online) and no solution at all!
8. Last attempt on reuploading my 481 MB world, level upload finished successfully, and then it says “Failed. An error occurred”. (This it actually my second day already!)
9. Purchased a new world, "Dragon Fire 2 Nations" in Minecraft Marketplace.
10. Replace world on my newly purchased realm subscription.
11. Can't upload again, error.
12. Tried to close realm, it says FAILED TO CLOSE REALM
13. Tried to create a world, on that new realm, ERROR TOO!
