Click on "Clear History"
Enabling this feature will remove the effect of all the Push-notifications that have been snoozed earlier
If a user snoozes Push-notification of a Guide, the Push-notification remains snoozed for one hour.
You can clear the snooze history from here and Push-notifications will again start appearing wherever you would have configured them
