How do I block Activities during a Focus Session?

To categorize an activity as distracting, which will block the app or website during a Focus Session, first go to your Activities Page. Hover over the websites and desktop apps you'd like to block and use the arrows that will appear to move the activities to the Personal Activities column. Any websites or desktop apps scored or ranked as Personal Activities will be blocked during a Focus Session. 

If you no longer want to block the activity, hover over it and use the left arrow to move it to Focus Work or Other Work.
