Keeping track of your overall Project Status can be done at a high level on the Mobile App while still allowing you to drill down to the Task and Issue level. To get here is easy - just choose which Active Project you want to view!
Get a high level "Dashboard View" of your projects on the Project Details page, from there you can get a breakdown of the Work Items within each project.
Drill down to Task Statuses under each Project allows you to see all tasks for the project to update, or you can use the My Work section to just see tasks assigned to you.
All Tasks will give you a breakdown of all tasks on the project by Work Status. You can update tasks by drilling down through the pie chart or on the Work Items section.
Issues will show you the issues associated with the project (if any).
Documents shows you files uploaded to the project.
Add Comment lets you make a comment on the project level and shows any past comments made below.
