I only have the Nintendo Switch Lite so yeah. Sorry if this is a dupe, I just want to know how to use it on a Nintendo Switch Lite.
You can't use Veevee Volley or Pika Papow in a Switch Lite, or even an undocked Switch without the controllers removed, because it is motion exclusive, meaning you need to wave the controller for it to work. Because this is impossible to do On the Switch Lite or the Switch with the controllers attached.
If you can connect other controllers that aren't attached to the Lite, it will let you use these moves though. Thanks TY! Source: https://www.reddit.com/r/PokemonLetsGo/comments/9y3cey/veevee_volley_in_handheld_mode/
