When it come to Check-Ins, there is no requirement for you to check out. We create new sessions for you every week so you don't have to check people out in order to be ready for the next week.
However, there is a workflow if you're using Roster Stations where the ability to check out people in bulk is incredibly helpful, and we've made that a lot easier. That situation is where children check in for one time in the morning, are released to their parents, and you want to have a second check-in for those same kids on the same day.
That's now been made easier with the new checkout all button.
Also, if you've filtered to a specific location, the check out all button will only check out the people you're filtered to.
