addon and realms bug

Realms bugs

First, the world data of Realms is more than 400mb, but it is not applied due to a bug even if the backup world is corrupted and you try to apply the backup world. Moreover, Realms cannot be opened at all temporarily.

Next, regarding add-ons, if you add an add-on of 200 mb or more, it will become an export and infinite loading will start. It's painful to me. Moreover, if you forcibly terminate it and open Micra, you will be temporarily disconnected from Realms.

After that, some features of the add-on are clearly limited compared to the ordinary world.

I'm using the battouken add-on as an example for this, but while it can be handled satisfactorily in the normal world, the functionality is limited in the realm no matter what. I will post the URL for this, so I hope you can actually compare and try it there. There is an add-on in the summary column.

Realms are very unwieldy, so please fix it. By the way, backup related Windows 10 version seems to be done smoothly, so I think it's clearly a smartphone version defect.
