I have checked trigger/history and there have been all triggers for the places I entered. So triggers apparently works the question is why I don't receive notifications? The first place I enter at 5:39pm, second at 5:56pm, third at 6:12pm and so on. Apple could rate limit triggers? that is something new for me could you tell me some more about that how it works?

In our testing, we found that the iPhone 3G and 3GS have native location services that are much less accurate. Often the accuracy of the raw GPS data is quite poor. Apple has made many improvements in the iPhone 4, and even more in the 4S, due to the new chipsets used for GPS and wifi-assisted positioning. In general, the better the native capabilities of the device, the better our triggers will work as well. As such, we have seen the best performance on the iPhone 4S.

Some Notifications Received, but Not All

If you are sending multiple notifications to the same device or computer within a short period of time, the push service will send only the last one.

Here's why. The device or computer acknowledges receipt of each notification. Until the push service receives that acknowledgment, it can only assume that the device or computer has gone off-line for some reason and stores the notification in the quality of service (QoS) queue for future redelivery. The round-trip network latency here is of course a major factor.

As described in the Local and Push Notification Programming Guide, the QoS queue holds a single notification per app per device or computer. If the service receives another notification before the one in the queue is sent, the new notification overwrites the previous one.

All of this points out that the intent is that a notification indicates to an app that something of interest has changed on the provider, and the app should check in with the provider to get the details. Notifications should not contain data which isn't also available elsewhere, and they should also not be stateful.
