Why isn't NoFall working?

[Dyiing]

NoFall will not work if you are wearing an elytra, due to how they work. If you do not have an elytra on and you still take fall damage, it's most likely an issue with the anticheat of the server you are on. Try the other NoFall mode and see if it changes, or try in Singleplayer to ensure the server is at fault.
