When replacing my world on a realm with another world it says "error". Tried replacing my world for two days now and it still does not work.

When replacing my world on a realm with another world it says "error". Tried replacing my world for two days now and it still does not work.

I have a world that I would wish to replace a previous world on Bedrock Minecraft Realms. However, when I get to the "initializing download" part of the process it either stays on that screen or says "error". I have been trying to replace world multiple times a day, but I cannot seem to get the world replaced. Keep in mind, my world has 945mbs of storage on it.
