How to scheduled push notification ?

In PlayFab, you can use the Schedule Task to send push notification in specific time period without defining the trigger. You can use the Rules to set a trigger, which immediately executes action (send push notification) when defined event occur, but there is no configure in delay time of triggering action. Sending a push notification after 2 minutes of calling SendPushNotification is currently not supported. If you would like this feature, you could post a thread in the Feature Request forum.
