Localization settings can be used to set a default timezone and Do Not Disturb Hours. Do Not Disturb Hours mute notifications at specific times.
Admins can set these up.
Please note users will not receive email notifications when Do Not Disturb Hours are over - notifications will still feature in-app in the notification's bell however.
Note: A notification will still be issued from a 'Send Push' as it's important people get the message. To update your organization's Do Not Disturb Hours, go to the Admin Dashboard Settings Localization.
