Hey @Black Spy, can you move the code to the thread when you get a chance? The subflow will be a different flow in the UI for Prefect 1.0. You have to navigate to the

hello-world

flow run

Code wise its working properly but in UI alone we have issues @Kevin Kho

Ah I see, do you have a lot of tasks there? Could you take a screen shot of your UI?

sure @Kevin Kho

The subflow will be in another flow run in the dashboard you have to navigate to.
