Exporting world to Realms fails :(

When I export my world to my Minecraft Realm, it gets past the exporting stage, then when it's initialising the upload, a text box appears saying "Error. An error occurred". And this is a repeating bug that happens every time I try. This is not just exclusively for this world, it's for any world that I create on my IOS and other people have also been having on the internet. I hope I brought light to this issue and hope it gets resolved soon.

-Thanks!
