I joined a world a bit ago and found that I couldn’t use any emojis, custom or let alone stock, as they were disabled by the instance creator. Why is the control of this feature even given to the original host of an instance? One single person should not be able to determine the use of a silly tool of self-expression that was added into the game.
If they do not want to see it, then they can disable that function themselves and for themselves only. That would make sense. Imagine disabling the text box function in an entire instance. Why would you even want to do that?
