Nintendo has released a new 12.0.0 system update for all Switch systems. However, there is not much in the way of new functionality.
Nintendo’s official patch notes indicate that it addressed an issue with cloud backups. The full notice is as follows:
We fixed the issue with the save data backup feature, where in rare cases, the automatic backup of save data is interrupted if a communication error occurs during completion of the save data backup process.
