In Education Edition mode.

When you write the worldbuilder command, the command does not work correctly ...

That is, when you make the game rule immutableworld true ... Worldbuilder in survival mode does not allow building under any conditions (true and / or false), in creative mode it is possible to build under conditions (true and / or false).

For example, the mayfly team works correctly under true conditions, the player flies - regardless of the game mode, and if false, the player cannot fly - regardless of the game mode.

I do not know how long this problem has been, but I drew attention to it in version 1.16.0.66 minecraft pe, for android.

If this is fixed it will be very good, I look forward to the developers ...

I did not observe similar messages, except for my in Russian ...
