For load balancing purposes we do not store messages sent through API with the “devices” parameter that contains less than 10 devices in an array. Due to this, such messages will not be displayed in your Push History.
However, as it’s necessary to see push reports during the testing phase, there’s a Debug Mode that you can use during your tests. Turning Debug Mode ON allows you to override this limit for 1 hour and save such pushes in the push history. Debug mode turns OFF automatically after 1 hour.
