Assigning users to tasks in Visual Studio Team Services
<p>I've just joined my friend's Team Services account (free for the first 5 users account). If I visit the home page (<a href="https://XXXXXXX.visualstudio.com/Development/Development%20Team" rel="noreferrer">https://XXXXXXX.visualstudio.com/Development/Development%20Team</a>), I can see us both listed as Team Members. I can create backlog items/tasks and assign them to myself. My friend can create backlog items/tasks and assign them to himself. However, we can't assign each other.</p>

<p>Why could this be and any suggestions on how to resolve this?</p>
