I can't seem to find a way to show completed subtasks grouped with their main task. I get the display under the main task such as:
There are also 3 old completed subtasks that are not displayed
when there are tasks but I'm trying to figure out how to see those. I know I can see all completed tasks in various screens but I can't seem to hit the combination to be able to see them attached to their main task.
Unfortunately, old completed subtasks cannot currently be shown attached with their parent task. This is something that we definitely hope to improve on in the future.
Just ran across this limitation myself. I hope it is high on the list for the next fix. I have to write a status/summary report of what I've been working on, and could really use this info!
