Hi @Robin_Hn,
This is more of an Asana issue than a Clockify one: Asana does not by default assign subtasks to the project of their parent task, which is I’m sure why Clockify is not showing the project.
You could likely solve it by attaching the subtasks to the project - that would I’m sure have the project display in Clockify. (But it has its own drawback in that the subtasks then show twice in the project view.)
It’s possible you could find another time tracker that overcomes this Asana behavior but I’ll bet it’s unlikely.
