Hi
I've seen many automation topics related to my problem, but I haven't found a solution there, so maybe I'll give you my specific case.
I want to set up notifications for our helpdesk so that the assigned person receives an email a day, 12 hours and 3 hours before the deadline. The duedate option will not work because there is no specific time, so I added a timestamp for tickets. I created various limiting rules, but in each case I received e-mails for each case (e.g. 3 hours before the time I also received them for earlier ones). It may be simple, but I think I'm too confused in it.
On the screenshot, the original rule (separate for each time), without other IF rules
