On Clickup’s help center page for automation triggers, it lists “Subtasks Resolved” as an option and says: When ALL the subtasks are resolved on a task, an Action will take place.

There is a note that mentions it can only work on immediate subtasks but I really need a trigger option for ALL subtasks resolved because I want to use 2 layers of subtask.

At the moment, you have to use “Done” statuses to trigger subtask status changes via “Task Unblocked” automations. But that obviously means that because the immediate subtasks are “resolved”, that in turn triggers an unwanted automation to the overall parent task.
