background not loading

it has updated, the background is not loading so we can see blue only in the distance, it will load eventually but will take time. If you play in creative,in survival or anything when you move 25+ blocks the blocks in front are not loading or not loading quick  enough. We played online so via my server and by them, were all having the same issue. Al so villagers are sleeping next to or in front. of their beds. it can be slow too
