I don’t know, but nobody can join my world. It says incorrect world Id, for ALL my worlds.

SO pretty much much, I’m busy inviting people to my worlds, but they keep saying it’s incorroect world Id, and my friends too. (I obviously can’t get an image if im not the one that is seeing proof of this, I just know people can’t join.) And I don’t know a specific version. I believe it started when the first Update Aquatic iOS beta was released.
