The Push Queue screen displays all results from Push Synchronization Trigger.
When data is changed in any entity listed in Synchronization Rules with the delivery method of "Push and Batch" a Synchronization Trigger is executed. Each Synchronization Trigger consists of a guard condition that will prevent the unnecessary creation of Push Queue records when no data should be pushed to a mobile app.
The Push Queue records are processed via a Database Process which will check the Ownership Query defined in Entity Details to determine which user/device to send the data to and will create a Synchronization Task to process the Push Queue records for each user/device found. If for some reason the Ownership Query returns no data then the status message will show that no user/devices found.
