Cant upload world

Good evening,

I downloaded my realm world to play offline 2 days before 1.16.0 dropped. I updated and tried to upload my local copy to the realm world but am unable to do so as it throws an error. I can play the realm, I can download the realm world but not upload back to the realm. As someone who plays both online and offline this is a major factor for me and as a player who currently pays for a 10 player realm, I am now very concerned that my money is being wasted.

I have tried renaming the local world, clearing cache data, completely shutting down my nintendo switch which I am playing on, tried different wifis and network connections, I have exhausted all options available to me and am now frustrated and rather upset after trying for nearly 2 days to make it work with no success.

Please resolve this or provide me with a suitable solution that isnt something I have already tried, I beg of you. We have played the same realm for nearly a year and we dont want to reset the world.

 

Thank you in advance for your support,

 

Regards,

Jake
