under “notifictation” is “Task” , not “Achievement”
the notification for 10 days, 5 days, etc triggers only if the project is “Ongoing” , if the project is completed it should not trigger them.
the same happens with the “task” notification, if it is %100 completed there is no need for that notification to be triggered.
task notifications trigger even if the calcultion of 10days to deadline is not meet. I tested with a notification 10 dyas to deadline, and the deadline for yesterday and it tirgered the notification.
I suspect the same happens with the projects notifications, i tested it and it seems to be doing the same mess.
