Click the 'Archive' button in the top right of the Cohort detail page to archive the Cohort.
Once archived, the Cohort's conditions cannot be modified, and the user list will no longer be updated.
When a Cohort Cannot Be Archived
A Cohort that is currently used as a targeting condition for another feature cannot be archived.
You can check which feature is using this Cohort as a targeting condition in the detail conditions section. Remove the targeting condition first, then try archiving again.
