Okay, so I think that I know why it won’t work. The reaching of the pending reminder time does not update the ticket in the same way that saving it does. So reaching of the time out time does not change anything, notably, correct me if I am wrong. When creating a ticket with the relative time out as the same time that the trigger “waits” for, waiting is not the right word, the trigger is triggered.
After looking further I found that the reminder should be send when the notification is activated, again correct me if misunderstood the thread.
The notifications should already be enabled however are not received.
