Minecraft realms can't upload world

we have a world size of maybe 190MB and when we try uploading it nothing happens just a normal survival world we tried a smaller world 19MB and it still doesn't work we tried making a copy of the world and uploading it nothing works we searched up seems other people have this problem and there is no fix we spent 8 dollars even if its not a lot we still don't like wasting money so we would like either a refund or a fix we just wanna play on the same world when the owner isn't online cause he goes away a lot and doesn't always have time to get on.
