1 month has passed since the purchase of Zeroday, well, now my opinion about the client:
Work under AAC:
long jump - doesn't work
fly - doesn't work
killaura and antiBot - not working
AutoArmor, FastUse, - even NoFall does not work.
I'm honestly shocked, Creators please !!! make Zeroday with AAC and NCP support and add fly for this version.
(Server crash module - not worked)

7 days later

Get a different client for hypixel get novoline its the best fly speed and killaura works no ban and its op

    NikitaUsee Couple things:

    1. This client is mainly aimed at hypixel
    2. There are working AAC bypasses but you probably don’t have them configured
    3. Use glide and not fly iirc
    4. A new update is coming soon so chill
