My original switch lite broke. I purchased a new one. my data was saved so i transferred my user, downloaded AC to the new console. I contacted customer support and they gave me the instructions i will put at the bottom of the page. I tried step 2 a million times and it did not work no matter what combo if holding the "-" button down I tried. I asked my husband for help and he tried, instead of HOLDING the "-" button down, repeatedly clicking the "-" button. This worked immediately.
I hope this helps someone!
OK, I want you to follow these steps:
1.Select Animal Crossing: New Horizons and choose the user with the Nintendo Account that originally enabled island backup.
•In order to restore island data:
•Your Nintendo Switch system must have a stable connection to the internet.
•Your game must be updated to the latest software version (1.4.0 or later).
2.As the game begins to open, you will see a black screen with the Nintendo logo in the top-left. Press and hold the – Button when this screen appears.

3.If performed correctly, a message will appear that asks if you want to check for island data to restore. Select Begin.
•If you see Timmy and Tommy at the Nook Inc. reception desk, the button input failed. Close the game and reopen it to try again
.
•If you see a title screen with villagers walking around an island, then you may have already started a new island on your Nintendo Switch system. If you wish to replace this island with your island backup, you must first delete the save data for Animal Crossing: New Horizons from your system, then reopen the game and try again. Your new island will not be able to be recovered after you delete the save data.
4.Select Check to search for island data to restore.
•If island data cannot be found, it may be because your Nintendo Switch is not currently connected to the internet or you are not using the same Nintendo Account that was used to enable island backup.
5.If you enabled island backup for multiple islands, you will be presented with each island name and some details. Select the island you wish to restore on your Nintendo Switch system, then select Recover Data.
6.Select Yes, please to confirm you are ready to restore the selected island backup.
•If you started a new island on your Nintendo Switch, it will be lost and replaced with your island backup.
7.After your island is restored, the game will restart and you will return to your island.
