Are there threads specific to this new game? I can’t seem to find any, ditto for name of islands, etc. I don’t know where I can submit my switch code or the name of my island. I just keep seeing my last ACNL info.
General threads for the game are on this board. To enter your Switch code you'll need to go to "My Friend Codes," and to enter the name of your island you'll need to go to "My Towns." Both are under the "My ACC" section on the left sidebar.
