Once you've added a cohort, it's only bookable if its dates are open on the calendar. Here's how to verify and open availability.
Open a cohort's availability
Open the calendar.
Jump to the cohort's start date.
Check the dates aren't blocked. If they are, unblock.
Verify the cohort capacity matches room availability.
If a cohort isn't showing up in search
Common causes: blocked dates, the cohort is past its sales cutoff, or it's marked sold out. Check each in order.
