Hi,
I have some tasks that I marked completed, but I can still see them in my timer list. Is there a way of clearing this list or do I need to delete completed tasks?
Does this work? Expand the stopwatch view to the full interface. The click the work item select to get your drop down. There is a modify view button you can press.
From there you should be able to add a filter that ignores completed items.
Does that work?
That would be perfect but unfortunately I don’t see that button (i’m using version from windows store)
Ok, I changed the installation from Microsoft Store to standalone and this function works 
Yeah, our Microsoft Store version is a little behind. Sorry about that. 
Is there a way to do it on Android?
Unfortunately, not at this time.
