Realms Large biomes not working

Hello,

In realms when you create large biomes, there is no hint of a large biome. It is all just a default world created regardless if you choose the "Large Biomes" option.
This have been an issue last time I played as well for half or a whole year ago.

It seems incredible that subscribing to a paid service and then the one function that matters to me doesn't function, and haven't for a year or more.
Is there any focus on this issue whatsoever or do I have to rely on 3rd party server hosting?

 

Regards,
