Topic: Two Devices, one on-line account

So I have a Nintendo Switch at home and Nintendo Switch Lite for on the go. If I own both devices why can't they both log into the same on-line account and be played at the same time without getting an error message?

@srmacart76 The Primary & Non-Primary system is for one person using one switch at a time; Play on the TV with regular Switch, power down, resume playing same game on-the-go with Switch Lite. The two consoles have to sync with each other to update your game progress. If you could use both Switches at the same time, playing the same game, there would be a game save conflict. Plus, they don't want to make it easy to share one game with multiple consoles. I don't love it either, but that's their system.
