Hyper Nook/Hairdresser

hello fellow acww players,

a week ago i started playing acww again since i last played during my childhood and i just read in some tiktok comments that you cant get hypernook and the hairdresser function anymore because nintendo cut the connection to whatever (server, wifi, system) idk so i need more info on that bc that would be soooooo shitty :(
