I started on PSN. When the switch version came out, I didn't have a pc account to link it with at the time but I wanted to play with my friends on Switch so I started from zero with them to teach them the game. Eventually they stopped playing and so did I. I then came back and began playing on PC which has now become my main.
While the switch has the least amount of time I do still have some things on there I would like to bring over. Is the account merge most likely limited to just 2 accounts?
