This can be caused by a number of reasons, not necessarily a bug, so we'll need to narrow it down. Are you all playing on Xbox? Is everyone using the default graphics settings? Let us know what troubleshooting you've tried already so we can rule some things out! ^AM

Hello, sorry I didn't see your reply. Everyone is on Xbox and none of us have texture packs on. We have all uninstalled the game and made a new world but nothing fixes it. It is impossible to use an Elytra or a boat or a horse as the chunks just don't load 😕
