I have a private project hosted in Azure DevOps. Two of us are assigned Visual Studio subscription access, which works fine. We also have two users with Basic membership, and a number of users with Stakeholder membership.
All of these users are included in the appropriate groups, all have the required permissions to access our Boards (Agile) etc.
The problem is I do not appear to be able to assign any tasks to any Basic or Stakeholder level users. The only users that show up in the User dropdown on tasks are VS Subscription level users.
Everything I have read indicates that all users, including Basic and Stakeholder level, should be able to have access to and take part in Azure boards and tasks. Can anyone shed any insight into this problem?
