I too have the same issue. I'm using a digital version of the game. I've seen others play by using a disk version. I'm unsure how the disk version works, but that's what it looks like.

i found out its not developed for online yet. idk if thats true though bc i saw people post in game photos. i have the disk and still no luck.

dont work for me either

its not supported by pretendo, maybe in the future

nope becus pretendo not make the game online in the future can make online? [maybe?]★★★★★★
