You must have Coaching Tools Admin - Head Coach access to hide workout details.
Some coaches do not want parents or swimmers to be able to view the details of workouts, at least for certain rosters or squads. You can hide workout details for one or more rosters/squads if you are one of them.
Click Coaching Tools > Practices or Events & Competition > Practices in the side menu.
Click Settings in the upper right.
Click Hide All Workouts if you don't want any roster/squad to see workout details, or Edit an individual roster/squad, check Hide Workouts? and click Save.
When a parent with a swimmer in one of those rosters/squads logs in, when they view attendance for a swimmer in one of those hidden rosters/squads, the workout names will have a lock by them, and clicking them will do nothing.
Likewise, tapping a specific attendance session in the app will no longer show workout details. Instead, they will see "Workout details have been hidden from your roster group!"
When they tap the Workouts tab, they will not see any workouts at all that are hidden.
