Before you launch, open What to Do Next, the gold button at the top of the left menu. Clear everything under Required before publish, then run AI Review for the things a checklist cannot catch.
Next, switch to the Event Day Simulation tab and test your event on your own phone: scan the code, sign in as a contestant and enter a class, then sign out and back in as a judge and try scoring.
When nothing is left under Required, turn on Publish Event under Public Display Settings on your Event Dashboard.
