Hi Dustin, And, well everyone else that is a bit confused. Here's what's going on, from Workfront's perspective. When you have someone assigned to a task, there are actually 2 statuses: Task status & User status. Task status is the relative status that you choose: New, In Progress, and Complete (by default.) User status is more hidden so to speak, in that it's the "Work On It" and "I'm Done" buttons. If a task owner clicks on Work On It, they set the user status in motion, as well as the task status in motion, typically changing the task status to In Progress at the same time. However, the only way to actually complete the task, is to click I'm Done. Nobody else can officially say that you're done with a task, which is why it's a separate process. Also, I've seen instances like yours where setting the Percent Complete to 100 doesn't trigger the user status to update, the best 'work around' is to have a drop down menu for task status, and change it to Complete. I've yet to see this not work for the task owner. Anyways, I hope this perspective helps explain why this situation occurs. You're always welcome to call into our Support if you need additional assistance. Thanks! Dustin Martin Tier 2 Assigned Support Engineer Workfront
