if you are playing on any version that is 1.14 - 1.14.4 you will be kicked by anti cheat for apparent fly hacks
Actually, the recommended version is anything between 1.9.4 (not 1.8.9 or below or else the shield will be a wooden sword with negative durabilty) and 1.13.2 (most recommended version), meaning that any >1.14 version (including the upcoming 1.15 version) isn't recommended due to unstability (and thus kicking you a hundred times for flying, even when standing still).
