Good afternoon I want to report a bug that is quite annoying since when I connect to the internet to play in my survivor world, for some strange reason you happen strange things in the game, that is, when I want to break a block, open a chest, or just eat The action is carried out with a considerable delay, in addition to the fact that when I am in caves or I pass near blocks that are 2 blocks high without any blocks underneath, they can be crossed without more, but that only happens when I am connected to the internet within the game. 

 but that did not happen to me in versions prior to 1.16.221
