This morning updated to beta 1.16.210.56. Now when my son joins my survival world it's like he is in creative.
Error #1 - He can break blocks instantly like creative.
Error #2 - Blocks do not drop when broken, they disappear like creative.
Error #3 - When he breaks a block, it disappears on his screen, yet I can still see it and interact with it on my screen as if it is still there. If I break the block, it drops item on my screen and his screen although only becomes visible on his screen once I have broken it.
So frustrating every time you do an update it makes two player impossible. Please fix this.
