We have been testing ilime. Sometimes when pushing instant messages from the ilime website, the latency is under 1 min, even close to 5 seconds. However, often times the message does not come through at all. Infrequently, a message will come through after 30 minutes or more, and will surprise us.
When using the "Scheduled one time" push notification, we get nothing at all, ever. This appears to not be working.
