Once matches exist, the Assign Groups to Courts guide offers two paths:
Auto-assign — “Groups are distributed evenly across courts and match times adjusted so no games overlap.” The fastest option, and usually the right one.
Assign manually — “Tap a court on the map, then assign a group to it.” Tap a court, choose Assign Group, pick the group in Select Group, and repeat until every group has a court.
