Expanded parent tasks close when a sub-task is checked/un-checked
In the Chrome and Windows apps when I click the triangle to expand a parent task and then check off an item, the view resets and closes the parent task. If I have a task called "Make bread" with subtasks "Mix ingredients" and "Bake", I have to expand "Make bread", check "Mix ingredients", RE-OPEN "Make bread" and check "Bake".
We are aware of this, and it's a slight issue due to the refresh interval. It's designed to close sub-task on refresh, but since it also refreshes when you complete something, it does as you describe.
We will look into improving this in future updates.
