you don't need this app for new lego pokemon use it i look it up

Developer Response

Right you are! The only time you'll need the SMART Assist app is if your SMART Brick needs an update. Open the app, make sure to leave your SMART Brick on the SMART Charger and tap ‘Update Now’ in the app! ✨ - Jane, LEGO® Customer Service

My son got a Star Wars lego set with smart brick. Tried to connect, make accounts and register it. Sent us in endless loops. App is awful, will likely need to return the whole set and will avoid purchasing anything with it again.
