Reminders allow teams to stay up to date with status updates and keep work visible. It works best for full-time teammates who constantly work on something and therefore is expected to have a respective ticket.
Reminders will continuously check whether a person has any work in progress and ask for an update. A check is performed once a day when the user is in Jira.
It is possible to snooze it or turn on or off in personal settings.
Managing reminders
On the People settings page, you can turn on/off the reminders for each individual or use the bulk modify option to update settings across the entire org or particular team. You must be an admin to access this page.
