I discovered that for us the problem was because on the ‘trigger’ event we recalculate/re-schedule the notifications and clear the ‘old’ ones because we have to keep always the next 50 notifications keep alive.

But on android the ‘trigger’ event is fired in the application while the app is in background mode, what caused the actually triggered notification was cleared by the recalculate of the notifications. Therefore in the notification center it showed, but it was removed also in same time.

After I modified our ‘trigger’ listener to watch the status also, it works fine for us.
