How long has she been playing Animal Crossing? Maybe you just need your persuasion to make her give your Switch back
Over a month. Every single day. I can take my Switch from her. She wouldn't resist at all. I just feel bad making her start over. I did have the foresight to buy the game digitally with her account so the game is on the new Switch. Just none of the progress. And I added my account to her Switch Lite and downloaded a few of my games and saves.
I used to buy a ton of Switch games and I was really looking forward to xenoblade but, until they resolve this, I'm not buying any new games. Haven't purchased a new Switch game or even played my Switch in a month.
