Recently I have found myself entirely unable to download any save of my realm that is greater than 350 MB. Rather than download, I receive an error message stating that I am running out of storage, and that therefore Minecraft has restricted this feature. This is contrary to the fact that I do indeed have enough storage to download it. The file size is currently about 810 MB
